The bolt on "Shooting shots" won't appear

So, I have checked the script with the “done” script a billion times, and it’s OK, and when I drag and drop the prefab on the anarchy table the bolt appear. I think the problem is in the Input.GetButton, but I have no idea about. HAlp???
Thanks!

It was a spelling difference for me (the “void update” should have been “void Update”). go to the “done” section and compare the “done player controller” script to yours (that’s what I did). I knew unity was k sensitive but I didn’t know it was THIS sensitive. hope this helps
