Loading an SWF at a specific frame ? Not sure if it can be done

Hi All,

Is it possible to load an SWF at a specific frame?

When a button is pressed on my root SWF file, I want a holder (?? correct term, basically the empty movieclip where all my SWFs load) with instance name “main” to unload one SWF and load another SWF at a specific frame. What is the code for something like that? Basically referring to a frame inside of an SWF… PLEASE HELP!!
