Swf to swf controlling mc from a btn

hey guys.
well ive got two swf files which ive setup a localconnection between and all i can do with that local connection so far is send text to one another but heres what im wanting to do.
when the main swf is open ive made it u can load the 2nd external swf via controls shift+a and on that 2nd swf i have a button symbol which when the main and 2nd swf a loaded the the user clicks on that button on the 2nd swf i want it to unload the 2nd swf and start an animation playing on the main swf.

is ne one able to help me setup this up correctly and my localconnection name for both swf’s is “address_database”
