just an ordinary function()

But it doesn't work, I've been going nuts over this a while now..

Code:
------------------------------------
depth=0;

for (i=0; i<8; i+=2) {
   
   
   
    _root.attachMovie("singleHouse", "sh"+i, i+1);
    _root.attachMovie("sh1Shade", "sh1Shade"+i, i);
   
   
    height = random(50) +70;
    _root["sh"+i]._yscale = height
    _root["sh1Shade"+i]._yscale = height
   
    depth-=10;
    _root["sh"+i]._y = 360 - depth;
    _root["sh1Shade"+i]._y = 360 - depth;
   
    _root["sh"+i]._x = random(400) +580;
}
// HERE IS THE CALL
_root.sh1Shade0.nr();

------------------------------------------

//AND HERE IS THE FUNCTION
function nr(){
    trace("it works");
}

this.onEnterFrame = function(){
    this._x = _root["sh"+nummer]._x  + ((_root["sh"+nummer]._x / 10) - 30)*-1;
}
--------------------------------------------

I've checked spelling, checked that it actually exists, simplified to a ridiculous level, and it still doesn't work!
Does anyone know why?
