Variable to HUD

Recently got UE4, I added this part onto the main thirdperson blueprint, It works how I wanted, it launches the player in the direction they are facing, however they can only do it a certain amount of times. I did this using the variable I named as “will”, I then went to create a progress bar blueprint and tried to use my “will” variable, however, I could not place it there (says something about it being out of scope) I have provided an image so that anything I have not mentioned can (hopefully) be found.
