Unity is not updating my script/variables

**So I added two variables and two lines of code to my script, and now it does not update it in the inspector or when I run the game. Can someone please help. I feel like I am missing something or added something extra in my script. The two variables are the recoilX and Y. And the two lines are the ones that increase the rotationX and Y by a random number 5. Help! Thanks!*
