Need help accessing via ActionScript, a Layer in another SWF

Hi!
I am still fairly new at ActionScripting and self-taught. I’ve been searching the forums and can’t find a way to resolve this issue.
I have several swf files imbedded in a main swf ( I know nothing special) One of the swf files (call it map.swf) was created with Adobe Illustrator and is map of the world as an import. Each country is in its own layer. Thru a movieLoader the map.swf file is loaded into my main swf into a layer called base. I know I can access it as _level0.main.base for example. From a web page I want to pass the name of a country to main.swf which intern hilights the country in the map.swf. I use a LocalConnection() to receive the country’s name and this part works fine. However, I’m not sure how to either pass the country name to map.swf or create and call a function that resides within map.swf. Or is this ecen possible?

Thanks for any advice.
