I have a "small project" at school to create a small calculator with xhtml 1.0 strict and php. The result must be displayed on the same page.
When I put the code on http://validator.w3.org/check to be validated I get the fallow error:
Line 88, Column 9: end tag for "form" omitted, but OMITTAG NO was specified ✉ You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".
Thank you to anybody that's trying to solve my problem!
The code:
<?php
require_once('base.php');
require_once('functions.php');
?>
