Undefined Index Question [Resolved]
Posted: Thu Oct 10, 2013 8:21 am
Okay, I have a simple dice game where they can place a bet and if they match 2 or 3 dice, they win gold. Problem is, is I always get the error below. I'm not sure why.
Notice: Undefined index: bet in C:\xampp\htdocs\login3\dicegame.php on line 219
dicegame.php
It's just like with any other If isset GET statment, but this one isn't working properly and I don't know why. I've used forms a million times and the if isset statement and never had this problem.
