Buttons in External SWF's

Using Flash CS3 AS2.0

 [b]I need to know if it is possible to make a button in an external swf. file 
loaded in a Main .fla to link to another frame or label in another external 
swf. movie.[/b] If so, how do I do it?

 I have a main flash file for my website with a portfolio gallery with 9 
buttons.

       I have 8 external .swf files for all my galleries. (eg. branding.swf, 
packaging.swf, displays.swf, etc....)

       Within those galleries I have 9 buttons that make up each individual 
gallery.

       The buttons reveal a large thumbnail with some text that explain what 
the image is.


 In some of the galleries I have some text that want the viewer to be directed 
to another gallery to view another piece of artwork that relates to this one.

 These .swf files are loaded in my main flash file using the loader components.
 I thought I read somewhere that when you use the loader components, action 
code will not work.

 Do I need to change all my loader symbols to symbols that use the _movieloader

actioncode?

 Here is a look at my test site to see what I am talking about: 
http://manganinc.pieper.com/piepert/index.htm

 In the [b]Portfolio[/b] section you will find the gallery buttons and if you 
click on [b]Product Packaging[/b]
 (this is the first button), a .swf movie will load and 9 buttons slide down 
and when you click on the 3rd button over at the top Nutro MAX Cat Bags will 
show up,
 the text under the thumbnail will have text that reads "Also see the
[b]case 
study[/b] for this project."
 This case study has a invisible button on top of it and I want to direct that 
to the case studies page in my Main Flash file.

 Another link is in the 2nd button down from the top in the same gallery which 
is Autopage packaging. There is text under the thumbnail that reads:
 "Also see the [b]brochures[/b] and the [b] in-store display[/b] "
 Here I need the button to link to the at least just the brochures gallery and 
the displays gallery.
 In my MAIN .fla I have all these galleries lableled. Meaning in my action 
layer these sections are labeled to their according gallery name.

 Hope this makes sense. Please help me if you can!
