BIG help needed

basically i have my main movie with different stages on the timeline i want to access.

i am loading in external swf’s into this main movie.

from these external swf’s there are buttons inside them that i want to use to be able to access certain frames in my main movie.

but i cant get the button to work. im not sure what script to use on the button to make it work. any help would be appreciated!

also, is there a way of loading an external swf, but entering it say half way? ie to skip the animation at the start of the swf that would normally play and enter the swf at its later stage?

i hope this is clear enough…
