How do you use Exec output?

Complete beginner here.

I am trying to learn how to use Unreal for VR (because for some reason I always have ideas that are way too big) and I need to use the thumbstick to move. (as using a teleport locomotion wouldn’t work with my idea.) The problem is that, for some reason, MotionController (L) Thumbstick Up, Thumbstick Left, Thumbstick Right and Thumbstick Down all output with an Exec type.

Unfortunately, I wanted to use it as a boolean and them multiply it with another number to then move the character. From what I have read, Exec makes in sort that you can use the command line to activate it, but that’s all I know about it. Is there a way to turn it into a boolean, or another way to make it work?
