include does not work

I made a modular system in which each part of the pages are in a folder, the problem is that I have a page with a form that is inside a modal, this form receives information from the bank, when I just sow the form it works and when I run the modal page it also works, but when I squeeze the whole page with I receive the error in include

  

Warning: include (../form/formCriar.php): failed to open stream: No such file or directory in C: \ wamp \ www \ CRUD \ modal \ modalCriar.php on line 11.
