Strike 1. This belongs in script request.

but i was also asking why is this happening?

also you should have read this:

2. Search other forums!
Please, before posting a request, take the time to go to hbgames.org or creationaslyum.net and look through their script database, they have a lot more scripts then we do here. Link to the .org script archive is below.
