Setup Stamina Decay/Increase for my Rolling/Dodging

Hello. I currently have a stamina system that will depletes once the character inputs the sprint (Left-Shift button) and will increase once it reaches zero and/or the player lets go of the button. I also have a system with animation montages that will let the character input a roll/dodge (SpaceBar button) if they are moving or not. I have tried getting the animation montages to when playing lose stamina, but when I do it they don’t regain stamina. Any help would be appreciated, and I hope the screenshots help.
