need help with functions

how do you triger a function, i know how to write a function but i cant get my pawn to exicute it. help please!

I’m trying to do something like this

Function Walk()
{
setPhysics(PHYS_Walking);
}

Walk();

But the compiler gives me errors. This piece of script is inside the script for a pawn. I’m really new to unreal script so I know I’m probably doing something stupid like you can’t run functions in the pawn. But if that is true were would you run them? Since I am using the unreal runtime I can’t even take apart other characters to see how they work. The code I’m using for the pawn is below, thanks for the help.

// I'm WORKING! Wait, never mind
class ExampleBoy extends ExamplePawn;


function Walk()
{
setPhysics(PHYS_Walking);
}

Walk();
