comparisons and depth

[chicken king webforumsuser@macromedia.com]

sorry to post two questions in one day, but i have run into a second problem. i have a looping movie clip which changes _y position randomly with every loop. that is working fine. but what i want to do is is have it check on the first frame of that loop for its _y position and adjust its depth based on that location.
right now i have tried this code

onClipEvent (enterFrame) {
if (_root.dad._y<=200) {
_root.dad.swapDepths(1);
} else {
_root.dad.swapDepths(100);
}
}

which is on a mc in the first frame of the dad movie clip.
sorry if this is a dumb question. i have primarily done animation and am teaching myself more advanced code stuff.

actually what i am really looking to do is campare the _y of _root.tractor to the _y of _root.dad and if tractor._y > dad._y then the depth of tractor > depth of dad and if tractor._y < dad._y then depth of tractor < depth of dad.

any advice from out there???

thanks in advance.

sorry. i am a putz. i got it figured out. i just put this on an mc in the main timeline:

onClipEvent (enterFrame) {
if (_root.tractor._y>=_root.dad._y) {
_root.tractor.swapDepths(2);
_root.dad.swapDepths(1);
}
}
onClipEvent (enterFrame) {
if (_root.tractor._y<=_root.dad._y) {
_root.tractor.swapDepths(1);
_root.dad.swapDepths(2);
}
}


thanks for all the help y'all have given me.
