Timers?

How do you make a trigger work when a timer expires?

Event - Timer expires

Yea but then you have to choose a varible and I dont really understand what any of them mean and also if I choose one and hit ok then on the next screen it dosent show up and I cant hit ok.

you have to set your timer as a variable so you can do that

It must be a 'Timer' variable.

k I understand it now but how do you actually get the timer to show. I put countdown timer-create a timer window but in game it dosent show up.

'Show' the timer window after creating it.
