Complete Newb To Scripting

I have programming experience with C++ and Obj-C, but am new to this language. I'm trying to make a cool satellite thingy that hovers and follows me around. For some reason when I touch it, the thing won't go up and hover. Then it's supposed to come down on the next touch. However, if I sit on it, then the touching works. Any ideas? I'll get some code next time I'm on the game.

integer Hover = FALSE;

do_hover()
{
    if (Hover == FALSE)
    {
       // do hover set up stuff
        Hover = TRUE;
    }
    else Hover = FALSE;
}

default
{
    state_entry()
    {
        // do init stuff
    }

    touch_start(integer whatever)
    {
        do_hover()
    }
}

Ok.. not perfect by any means, but the touch event needs to switch something on and off.
