How do I prevent my audio from overlapping and playing many times at once?

I used the JJ weapons plugin to help set up my weapons, and I'm trying to make a reloading audio play when the character is reloading, but the audio ends up playing every tick that the character does. Does anybody know a way to help?

If you press a key to reload then that is a trigger once condition so you could play the audio there, or else you can add 'trigger once' condition to an event.

Can you please tell me how to set the trigger once condition?

On the event left block press C and add System > Trigger once

Thanks for the help mate!
