Syntax Help

[Nitefang]

hey all - I'm working on an idea and cant get my button script to work

what I'm wanting to do, is create a button that opens a custom window to a specific tab in that window- ideally, I'd like several buttons, each one opening the same window to a different tabbed page.... I've played around with the "ActiveTab" setting a bit - but my coding knowledge is very limited..

any help would be appreciated !
