Strange reason for rejection !

Hello guys i have been seeking help for a week because envato has rejected my item stating

Consider using at least a minimal framework to structure the application better. Right now, it’s a mix of HTML, PHP and SQL.

Now i don’t now whether they meant to the directory structure or code structure !! please help me what should i do ??

Hey,

An example:

mainfolder
-js
–js.js
-css
–css.css
-inc
–includes.php

etc etc
