Fall Damage Not Working

Ok. So I have this fall damage blueprint and it was working yesterday. I saved and closed out of Unreal Engine. Today, I opened it up, and when I tested it, it didn’t work. Can anybody figure out what is wrong with this? This blueprint is all in my character event graph.

I fixed it!! All I had to do was add it to the viewport as a variable in the same event graph as the other stuff (character)
