How to make a progress bar and it increase when picking up items?

This makes definite sense. I thank you for this!

One problem though. It still does not show up the progress bar. The only difference I made was the key binding being Left Mouse Click. But what I actually want is that My “tickets” get picked up whenever I collide with them. As you see on my last photo, The objects are already made and whenever I collide with them, they get destroyed.
