Why is this not working (Reupload from reddit)

this is for a mod that has a gui based minigame where you have to hold h to cover your ears (at the end) in order to survive, for some reason it does not detect when you hold h, whenever you press h it sets the variable to true and whenever you release h it sets the variable to false.
