Help with 2D topdown movment

Hi, I'm new to Unity. I started watching videos on how to create 2d top down movement with C# I copied the guy's script exactly double checked to make sure. And it didn't work. I checked and checked, but the script wasn't working. Everything looks fine but it still isn't working. The only thing I noticed that was different was that whenever he typed his code, his ode would be coloured. where my script only had white and a little bit of other colors. Don't know if this makes a difference or not, but that's all I can think of.

Oh and the 2 erros im getting are "Assets\PlayerMovment.cs(17,20): error CS1001: Identifier expected" and "Assets\PlayerMovment.cs(17,50): error CS1002: ; expected"
