terminate called after throwing an instance of 'NSException'

i'm kinda new to obj-c and cocoa touch so i don't really know why it's throwing the exception can anyone help decipher this for me?also if you need more code just let me know...i wasn't sure what to post here

It might be a broken connection in interface builder.

Try opening the XIB for WotT_Codename_SaviorViewController and finding something linked to CreateCharacter and I'll bet that's your problem.

You should define CreateCharacter property in your view controller and you should be good.
