I have the following HTML form:

  <form name ="form" class="signupform" action="signup.php" method="post" onsubmit="Valitedata()" enctype="multipart/form-data" autocomplete="off">
    <p><u>Create an account</u></p>
  <div class="form-container">
    <span class="input-label">Name:</span><input id="name" type="text" placeholder="Name" name="name"><br>
    <span class="input-label">Surname:</span><input id="surname" type="text" placeholder="surname" name="surname"><br>
    <span class="input-label">Email:</span><input id="email" type="email" placeholder="Email" name="email"><br>
    <span class="input-label">Door Number:</span><input id="doornumber" type="text" placeholder="Door number" name="doornumber"><br>
    <span class="input-label">Road:</span><input id="road" type="text" placeholder="road" name="road"><br>
    <span class="input-label">Post Code:</span><input id="postcode" type="text" placeholder="post code" name="postcode"><br>
    <span class="input-label">Password:</span><input id="password" type="password" placeholder="Password" name="password"> <br>
    <span class="input-label">Confirm Password:</span><input id="cpassword" type="password" placeholder="Confirm Password" name="confirmpassword" autocomplete="new-password"> <br>
      </div>

And I'm trying to validate in javascript:

function Validatedata()
{
    var name = document.Validatedata.name;
    var surname = document.Validatedata.surname;
    var email = document.Validatedata.email; 
    var doornumber = document.Validatedata.doornumber;
    var road= document.Validatedata.road;
    var postcode = document.Validatedata.postcode;
    var password = document.Validatedata.password;
    var confirmpassword= document.Validatedata.confirmpassword;
    var country = document.Validatedata.country;
    var Address = document.Validatedata.Address;
    var firstName = document.Validatedata.firstName;
    var lastName = document.Validatedata.lastName;
    var Email = document.Validatedata.Email;
    var MobilePhone = document.Validatedata.MobilePhone;

    if (name.value == "")
{
    window.alert("Please enter a name.");
    name.focus();
    return false;
}
   if (surname.value == "")
{
    window.alert("Please enter a surname.");
    surname.focus();
    return false;
}  
       if (doornumber.value == "")
{
    window.alert("Please enter door number.");
    doornumber.focus();
    return false;
} 
    if (road.value == "")
{
    window.alert("Please enter road.");
    road.focus();
    return false;
}  

   if (postcode.value == "")
{
    window.alert("Please enter postcode.");
   postcode.focus();
    return false;
}  
   if (country.value == "")
{
    window.alert("Please enter country.");
    country.focus();
    return false;
}  
   if (Address.value == "")
{
    window.alert("Please enter Address.");
    Address.focus();
    return false;
}  

   if (firstName.value == "")
{
    window.alert("Please enter firstName.");
    firstName.focus();
    return false;
} 
   if (lastName.value == "")
{
    window.alert("Please enter lastName.");
    lastName.focus();
    return false;
} 
    if (Email.value == "")
{
    window.alert("Please enter Email.");
    Email.focus();
    return false;
}    

   if (MobilePhone.value == "")
{
    window.alert("Please enter MobilePhone.");
    MobilePhone.focus();
    return false;
} 

}

But this validation I created is not doing anything. I would like to say that this validation has other "var" because I want to use the js file with other forms.

Some idea of why it is not working.

Missing information on your question so I've looked at your code. But from the information I have, you can do it as follows

function validateForm() {
    var name = document.forms["form"]["name"].value;
    var surname = document.forms["form"]["surname"].value;
    var email = document.forms["form"]["email"].value;
    var doornumber = document.forms["form"]["doornumber"].value;
    var road = document.forms["form"]["road"].value;
    var postcode = document.forms["form"]["postcode"].value;
    var password = document.forms["form"]["password"].value;
    var cpassword = document.forms["form"]["cpassword"].value;
    
    if (name == "") {
        alert("Please enter a name");
        return false;
    }
    
    if (surname == "") {
        alert("Please enter a surname");
        return false;
    }
    
    if (email == "") {
        alert("Please enter your email");
        return false;
    }
    
    if (doornumber == "") {
        alert("Please enter doornumber");
        return false;
    }
    
    if (road == "") {
        alert("Please enter road");
        return false;
    }
    
    if (postcode == "") {
        alert("Please enter postcode");
        return false;
    }
    
    if (password == "") {
        alert("Please enter a password");
        return false;
    }
    
    if (cpassword == "" || cpassword != password) {
        alert("The password does not match");
        return false;
    }
}

<form name ="form" class="signupform" action="signup.php" method="post" onsubmit="return validateForm()" enctype="multipart/form-data" autocomplete="off">
  <p><u>Create an account</u></p>
  <div class="form-container">
    <span class="input-label">Name:</span><input id="name" type="text" placeholder="Name" name="name"><br>
    <span class="input-label">Surname:</span><input id="surname" type="text" placeholder="surname" name="surname"><br>
    <span class="input-label">Email:</span><input id="email" type="email" placeholder="Email" name="email"><br>
    <span class="input-label">Door Number:</span><input id="doornumber" type="text" placeholder="Door number" name="doornumber"><br>
    <span class="input-label">Road:</span><input id="road" type="text" placeholder="road" name="road"><br>
    <span class="input-label">Post Code:</span><input id="postcode" type="text" placeholder="post code" name="postcode"><br>
    <span class="input-label">Password:</span><input id="password" type="password" placeholder="Password" name="password"> <br>
    <span class="input-label">Confirm Password:</span><input id="cpassword" type="password" placeholder="Confirm Password" name="confirmpassword" autocomplete="new-password"> <br>
    <button type="submit">Criar Conta</button>
  </div>
</form>
