Couple of Questions

[MrBigzy]

Er, this code would just set more integers, not create a string. Is there any reason why you would want to do that conversion? Are you trying to suffix strings for multiple callbacks?

Also for your first question, I'm pretty sure the boundaries of the area are the only thing that trigger the state and not the area itself. I could be wrong though; you would have to do some testing if you need to find out. Doing a debug might give you a message telling you whether you entered it or not.
