Hello,
If you are using a script made by someone else, it's usually best (faster) to ask him/her/them, since they are the one who know the script inside-out. But if you are having problem modifying it, etc, then you could also post it in a corresponding forum (e.g. PHP, ASP, Perl... The language your script is written in). If you need a script, as others say, please post it in the script request.
Welcome to the forum. =)
