Error: CS1525 Cant find cause. (Absolute beginner)

Ok so I’m trying to make my first game/prototype which is a top down 2D game. Now i found this tutorial (Unity 4.3 2d topdown game tutorial for beginners - Animation System - part 6 - YouTube (script at 3:27)) for movement and I’ve gotten rid of 3 errors now but can’t fix the last, please help I’m an absolute beginner. Script:
