Inserting Navigation SWF into FLA

I’m currently developing a full flash site. I’ve made the dropdown navigation menu with flash also. However, whenever I insert or import it into the webpage .fla, nothing works. When I preview the navigation menu swf file it works perfectly, ie, the mouseover effects, however I lose all actionscript coding when I bring it into my webpage .fla, what am I doing wrong?

Thank you sooo much in advance for your help, I’m ready ot hit my head against the wall!
