Kid, check the dates on threads you're replying to. This one was resolved well over 2 years ago.
But do tell, is it a new sport somewhere to create forum accounts just to post nonsense to age old threads?
I've been seeing it a lot lately.

Javascript is amazing, I didn't think you could touch mysql with it!
Everyone kept telling me to use php with my js to get into sql.
HAHA I feel like a million bucks!
