Variables and triggers

Hey, I am making a Tower Defense, and I need to find a condition. How do I make this trigger?

Code:

set ingameplayers= (all players matching (((matching player)slot status) equal to is playing) and (((matching player)controller) equal to user)))

It's the and condition I cannot find.

Well, there's a condition called "and"... start with that one.

Thanks a lot AceHart ^^
