Script Area triggering twice? Why?

[Mudbill]

The last number, 0 in this case, is the state this event is executed at. If you read on the syntax, it says 1 = enter, -1 = exit, 0 = both. So you should change that number into 1 to have it only run when you enter the area.

Edit: Looks like daortir beat me to it xD
