Why isn't my basic input script working?

I followed the videos to make my animations move. I have initiated the anim component, Set a move variable to Input Horizontal, set a Speed variable set to a running animation and, set the transition if speed is greater than 1 then play running animation. Another thing is that no sort of input works. The animation works if I set it as the default animation, but I test if I hit the space bar then the death var in the animator is set to true and plays a death animation that doesn't work either. I checked the Input settings and its set correctly. Can someone give me some insight?
