How do I use progress bars?

Hi everyone.
I’m pretty new with the UE4 and I was trying to create a HUD with two simple progress bars for both health and stamina. The issue I’m facing (even if I followed step by step the documentation Epic Games has released about this subject) is that whenever I hit play the progress bars don’t show anything but themselves. Can someone help me, please? I do attach the photo of the “result”, the HUD BP and the character BP.

Did you set the default progress value of each progress bar to 1.0 that way the progress bar starts off full?

Oh, that was an easy one… No, I didn’t set it to 1, thanks… But I still miss something… I set that when F is pressed, it “receives” damage of 25 (default is 100). I know that I lose life because when I hit the zero it quits the game, but it is not shown on the HUD… ! I attach the BP of this thing

When you take damage you also need to update your HUD widget with the progress bar.

If my answer helped you could you mark it as accepted so other people know it worked?
