How to stop my Z Vector/Jump in midair

Hi there I was able to create a Titan jump from Destiny but, I’m having a problem not being able to stop Z Vector/Jump in midair when gliding up.

Please see image below for Blueprint.

Any help would be Awesome:)

You don’t need to do any of this to get double jumps. Just set these variables in the character:
