Main>swf>swf's help/advice please

Hi, I’d appreciate some help/advice on getting seperate swfs(3,4,5) open[from a button] when called from a swf(2) loaded into a main swf(1)
ie: main(1)>swf(2)>swf’s(3,4,5)

this is what I tried…

on(release) {
loadMovie(“3.swf”, “_root.placeholder2”);
}

I can’t figure it out, any suggestions?:puzzled:
