loading external swfs from an external swf

im building a site that uses a simple AS to load "contact us.swf" into the main movie. my question is how can i code it that from "contact us.swf i can load another external swf such as "form.swf"? i cant get it to load the form heres the code im using
from the mainmovie
on (release) {
_root.contents.loadMovie("contact us.swf");
in the contact movie
_root.contents.loadMovie("formswf");

any suggestions?

Other than the typo, what your trying to do is to load another swf into where the first one is, from the first one. should work, but not this way;

_root.contents.loadMovie("formswf");

Should be;

_root.contents.loadMovie("form.swf");
