Controlling multiple widgets in game?

So I have a menu set up like duantless to when I hold down Left bumper my hotkey bar for abilities show up. But When I press a game face button (X, O, Triangle, Square) that the slot is assigned to nothin happens. Ex: I press X to shoot fire ball but instead of doing the skill my character still jumps. How do I override the basic functions? Or have it where when that menu displays the other basic functions cease? I have been stuck on this for days and have know Idea how to get around it. Any advice would be greatly helpful!
