How to Jump again if in event overlap?

CORRECTION - FIXED: Correction: I guess I had to change it to “get player controller” instead of get player character for the on component begin/end overlap section

Okay, so I created a blueprint with a Cube and created a big Box collision around that and am using that for the begin and end event overlap. What I want to do is when a character enters that box collision, they can then jump. This way, if they jump through the collision, they can jump one time until they exit and reenter the box collision.

I can not find an “enable jump” option or anything to do this within the Cube blueprint. Any ideas?

this is currently what I have: it works in the characters blueprint, but not in the Cube’s blueprint.
