Ok,I am making a lift, it goes up but when i place settimer it does not come down.

I think the problem i having is this:

forward Lift();

The forward word isn't blue in my GM !
Or maybe it doesn't need to be blue?

'forward' is not blue indeed

Maybe you could take a peek inside the elevator FS included in the SA:MP package.
Also posting the code might help us.

Just show me a TUT with Settimer . Like a gate opens and closes (only 1 command)
