Nevermind

Apparently when I change it back to '13' I get the same error message which must mean this error was happening before I started changing the 13 to 18. The only modifications that have been done were the Arcade hack and I followed directions closely and ran into no problems and the arcade games work great.
I want to turn my vBulletin script into a dating script with zipcode searching, picture uploading, paypal payments, etc. But since no one wants to do this project for me I am left trying to figure out how to do it myself, but apparently I am having problems possibly before I even started.
