Character Controller Problem

hello…
I was using unity3d 1 years ago… i learned the basics but i had work to do so i didnt had time…
Now im ready to master it. So i started today again to remember the basics.
And i occur a problem that i didnt had in the past…
I create a ‘capsule’–>‘add component’–>‘scripts’–> ‘character controller’
and i got something like this:

I press play… i try to move it with w,a,s,d but nothing happens… it doesnt move…

Whats the problem with it?

Thanks in Advance

Not sure, but you might need to define the inputs for those buttons.
