if(Input.GetKeyDown("UpArrow"))

{

moveDirection.y = jumpSpeed;

}

p.s. please help!

It's unknown because you haven't defined it anywhere. You need to define variables before you can use them.

Try this.

var jumpSpeed = 5.0;
var moveDirection : Vector3;

if(Input.GetKeyDown("UpArrow"))
{
    moveDirection.y = jumpSpeed;
}
