Flash to dreamweaver problems

Hi

I realy need some help to sort this out. I have put all the swf files into DW in a fla folder. then i create a main html page and put the main.swf in it.

it works fine but the main.swf has external swf files to make the main.swf complet. it all works fine in flash player but when viewed in DW it only plays the main.swf and will not play any of the external swf WHY???
