Btn function in loaded swf to go to frame on timeline of loading swf

Hello Everybody

I would need help with following functionality:

An external swf file (swfEx), which contains a button, is loaded into another swf file(swfLd). When clicking the button contained in swfEx, it should navigate to a certain frame of the main timeline of the swfLd movie and at the same time remove swfEx from swfLd.

Thank you for your help
