So I can't get the console to work properly. I type player->setspeed65 and get this error

Script sys window compileandrun script command setspeed65 not found on line 1

Before you ask me why i'm cheating, i've beaten morrowind several times, i'm just playing around with builds to waste time before skyrim.

Try;

Player-> SetSpeed 65

It won't compile SetSpeed65 because it's looking at the command as all one function.
