How to play sound once

Hello. I have made 2 trigger boxes one to open a door and the other one to close it. But when i walk over the 2nd one [the one to close the door] it works and everything just if i go back over that trigger box it replays the sound and wanted to make it so it only happens once. heres a picture

If anyone can help would be amazing <3

You probably want a couple sequences and do onces.

Although I see you are using the end overlap. You may want to check if your matinee is still playing before allowing anything to happen.
