Calling function on a yet to be loaded .swf

Hey everyone,

I am a designer so my programming skills are very limited. I have an issue that I’m losing my patients over, so I need your help. I went through a bunch of tutorials, none of them seemed to apply.
I have put together a sample (“sample_site”), if you would check it out, I would appreciate it.
You might ask, why did I use this many UILoaders, it is because on the original site I use a third party component, which doesn’t work well with frames. So frames are out of question.

If you open “main.swf “and click “home_btn”, you’ll see “home.swf” load in, containing 3 buttons. I want these buttons to load in “portfolio.swf” and trigger the corresponding buttons.
For example: clicking “home_green_btn” triggers “sectionLoader” to load “portfolio.swf” and call the function of “portfolio_green_btn” called “portfolio_green_Click” which loads “green.swf”

The closest I could get is, to get “home_green_btn” to go to “portfolio.swf” by calling on the “gotoPortfolio” function, which I scripted into “main.swf”

You tell me if it’s possible. My best guess would be the use of Local Connection, but I couldn’t figure it out. If you have a solution and you could upload an updated version of my sample site, that would be great.
Thanks!
