Re: Select Correct Video Source from Select Dropdown List

A script like that can't be debugged in a form like this (if staring at code were a productive debugging method, there wouldn't be nearly as many bugs as there are). You will need to add into the script stubs revealing variable values at particular line numbers, and walk through it till you find the problem.

What I can say is that ...

> $results = mysqli_query($con, $query);

... is dangerous in that it does not handle errors---you need code for the case that mysqli_query() returns False and mysqli_error($con) returns error info.
