Trying to make Shift increase movement speed, can't get it working

Hey there!, I’m trying to make a pretty basic 2D RPG style game, and having a bit of trouble right off the bat!

I’ve got a character controller that works, I can move around, what I’ve tried to do is add a Sprint function (Hold shift, you walk faster).

This is what I have, but pressing Shift does nothing, I’m sure it’s a super simple mistake somewhere that I just need someone to point out!.


Many thanks in advance!

compare these docs,

Oh!, That’ clears things up, Much appreciated.
