Save value to an input after inserting it automatically using Javascript

Navigation
1

I have a select box that defines how many items are going to be displayed to the user.

However, when it fails to fill one of the inputs, it displays the error: "undefined" If it fills the 5 fields, they work fine, the problem is when the user chooses less field.

How do I collect the value of the inputs and not display this error?

Instead of using multiple variables to fill in the result, you can fill only one containing the text, and verify that the input is valid.
