Open / Close Door with TriggerBox, TriggerBox not reconize


I create this script in the level BP to open a door with a matinee when I press the F key and with a flip flop to close it.
That work BUT the TriggerBox dont seem to be reconize…

In the game, I can press F from anywhere on the map and the door open and close…

An idea ?

Thanks a lot !

I have used this tutorial and this works fine
