Need help with Collision and Bars

I am having an issue when a block hits the player. I want the player health bar to be reduced by 1 on collision hit, but no matter what combination of things the bar always gets taken to 0 instantly instead of decreasing incrementally upon hit. Here is a screen shot of my “code”.

The bar’s value is set to 15 and the collision reset timer is set to 10.

bump I’m stuck send help plz

Post a link to your game, and we can take a look. - I seem to have found another issue with the Game Title not saving and the Stage X/Y size reverting back to default after I’ve changed it to a bigger area. WTF this app is super buggy

rip this app
