[quote author="TheFuzzy0ne" date="1236268757"]Haha, I was just about to say that. But I'm not sure why it should be the problem, unless of course you wanted to add variables that weren't already defined.[/quote]

It was returning false because I set the variables in my class to Null. There are 2 ways for me to fix it.

1. remove isset check
2. when declaring my values don't make them null instead declare them like pass = "";
