Loading external swf files

i’m loading a game level as an external SWF so that i don’t have to load the entire game as soon as the player clicks start-

however, the swf works fine but it taking sound information from the swf it was loaded into- rather than using it’s own sounds (some sounds have the same names- but since the sounds are built into each swf i’m not sure why there is crosstalk).

any tips appreciated! i need the sounds built into each swf to work only for that swf.
