How to use shared library?

Hello my genius friends,

I used the word genius because I got solution here everytime i post an issue…
Hope you people help me this time also.

In my child swf I am using the sound from library with “attachSound”. I also use the play/pause button controls of this sound alongwith the other animation.

Now when I load this into my main swf file with “loadMovie”, It plays fine but no sound. I found that this is due to no sound linkage in my main file library.

Now the issue is that I want to share my child swf’s library with main file’s library. I have no idea how to do this. Any help please??
