Play sound upon hitting a variable instead of while

I'm having a problem, I want to set a sound to play at my game when combo multiplier hit X, but the way I made the combo multiplier system, its like the game will play the sound forever when the variable is above X, and not only one time.

I want to make it play once, like a trigger. And then stopping. Not mattering if the X value remains the same or even goes higher.

What can I do?

There a system action for "Trigger Once". It will cause your current event to run once while all of the other conditions are met.

Worked like a charm, thank you!
