No collision between character & columns

Hello Again!
I’m still trying to get my project back to how it was, before I had to delete and reimport the opponent character, “Kristi”, due to my erroneously setting her as a global object. I think I am close now. I’m pretty sure all the events are back to how they should be. BUT WHEN I HIT “PLAY”, THE CHARACTER STILL RUNS OFF OF THE RIGHT SIDE OF THE SCREEN. I NEED TO HAVE HER RUNNING BACK AND FORTH BETWEEN THE COLUMNS. I don’t see any behaviors or variables on the columns. Is that the problem?

On collusion you change scene variable left.
But you use object variable left to move her.
Those are not related variables

Thanks, that was it!
