[SOLVED]How do I Stop Actions From Looping

Hi All, just a quick problem with actions looping, I have a black fade appear when the player completes the level, but I only want it to appear when I wish ( namely when a certain sprite has gone that the player created ) The problem is because this is always true it keeps running the action. Any ideas how I can work around this? Thank you in advance.

Add condition: Trigger Once

DuckfaceNinja , Thanks so much for the reply, this action stops any of them running however. The actions run without it so I know construct recognizes that the conditions are met, so I don't understand why when I add the Trigger once command it stops any of the actions from running. I feel I'm making a noobish mistake that's staring me in the face.

DuckfaceNinja, Ha I was right, forgot C2 runs actions from the top down so having the trigger once action at the top stops it from running, putting it at the bottom works. Thank you very much, your a life saver!
