I'm having this problem.
Notice: Undefined offset: 0 in c:\web\php4\wbmb\include\scheduletablebuilder.php on line 119
This is an iterator script.
Here is the entire code, with the problem line emphasized between comments
I had this problem before. And I just had to fix a conditional. However this time it seems all conditionals are correct, and I don't know what to do now.PHP Code:<?php
error_reporting (E_ALL);
