VR Player won't trigger a box trigger

Hi its me again. I have an issue where I make a box trigger that is the size of a small room and when the VR player walks in the lights in the room are suppose to flicker. But at the moment I can’t seem to get the lights to flicker. I made sure the lights were on dynamic and that it looked for my specific VR player character to overlap and then end the overlap. But so far no progress.

This is my code. It’s suppose to change those 3 lights and randomize the delay and the intensity. Then when the player leaves it breaks the loop I had up above. Is there an issue with my logic?
