Need help health bar slider

I am trying to make a music/rhythm game. I have been following "gamesplusjames" tutorials on Youtube, but he didn't upload any new ones in months. Wonderful tutorials.

I am using a slider UI for my health bar and a text UI to keep track of my health points. The health tracker text works but the health bar slider doesn't move. It stays at the value of 3 as my starting health even if you change the value to max 10. I already linked my slider to my GameManager's Inspector.

Ignore the score and multiplier system... those works perfectly at the moment

Not sure if this mean anything when moving the slider manually...

nevermind I fixed it... i put the health bar = current health points in the wrong place

Here is the updated code. Mostly codes from the tutorial anyways but with a few stuff added into it. I still got a lot of stuff to work on.
