null reference but component shows up in the inspector.

I am getting null reference exception

when debugging. It returns the component and then after says it is null. I ran it in update and it just goes back and forth between the component and null

https://s16.postimg.org/yhlzx2o1x/Capture.png ][1] << link to images to show you what im getting. Its saying that the playermove is null. I debugged it. and even initialized it at the point of the error if it returned null. it keeps saying its null and not working. the variables inside the script are public as well.
