The Hurt Function isn't working on a different scene

It is me again with another collision question. ( I know, shocking ) Anyway, while I was working on my game I encountered a problem with the enemy collision. On my original test scene the enemy collision works just fine. The player will get hurt by the enemy and will die in three hits. However, when I moved over the player and the enemy over to another scene ( any old or new scene ) the enemy won't hurt the player. I originally thought it was a problem with the tilemaps ( for I made a new one for the new scenes ), but I figured out after some testing that it won't work at all. I did start to use collision layers to help control collision, but the hurt still works fine on the original scene. The script for the player can be seen below.
