Problem with my Program/Game plz help

Hello first time here and I dont usually ask questions unless I really don't know whats going on so
Heres a link to the programs code (for now) pastebin.com/5efhQk2P
The problem is that when i type "Fight"
The damage randomizer works but the health still says 100
This is also the same for the enemy attack
IDK whats going on.
Any help?

You only need to use local once, when you use local again you are making a new variable

Thanks, it worked.
