Why isn't my countdown working?

Hello! I am quite new to Construct 2 and i'm having struggles with setting a countdown/timer. I've searched numerous tutorials which for some reason won't work. I tried the tutorials on other projects and it worked but why doesn't it work on this specific project? Thanks

I'm working on a Timer behaviour tutorial, but haven't got there yet. Here's the CAPX I'm working on. Sample 5 has a countdown timer.

well if you think about it countdown is like a reverse way to go forward in time so how about for every 1 sec minus one from a variable and then make a condition when it hit 0 to do an action.

You do something like If variable isnt 0 then for every 1 sec minus 1 from the variable. I discover it when i was making a spawn minion system

Thank you!
