Mail sends me a blank message and - php

Question

Hi everyone,
With this form you send and an empty mail if you click on the submit button which should actually happen. Before that whenever I fill in the description textarea than I you can't see the description but the rest of the details are ok.
So my question is what exactly happened?
This is the Modal:
<div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="MAXDATA Support">

Check your opening form tag. Try to put 'PHP_SELF' instead "PHP_SELF".
