trigger_multiple in a racing gamemode

Yeah, well i’m making a racing gamemode (hooray) and so far my attempts to add one to the lap counter when the player crosses the line has failed, and my friends has directed me to trigger_multiple, so how would i set up the trigger_multiple and a script to pick up when a car passes through it?

This might be of some use to you.

Thanks, but i already solved this problem by using checkpoints and a trigger brush.
