Telling the game an object is below or above another?

Hey guys!

I'm hoping someone can tell me how to do this. It seems pretty simple but I can't get it to work right.

Is there a way to tell the game that essentially if: Object A is above Object B to then move object A to a layer above object B?

Is there a way to just compare the two values of each of these, and if it's above that object by a certain amount, it can then shift it's layer?

Any help is greatly appreciated!

Try using this event :

Sprite - Pick top/bottom ---- Sprite - Move to top/bottom.
