loading a swf into another swf

i have the following problem, i load home.swf wich has a mc named "my_mc" into index.swf, in index.swf i have a mouse click listener that should hide "my_mc" but i get the error "my_mc" is not a recognize property , so how to get flash to recognize this mc named "my_mc" loaded in the swf?

You have to make sure the path is correct.

_root.homeswfinstancename.my_mc

Something like that.
