Load movie with print botton in main movie

I load a movie (movie1.swf) in my main swf (main.swf):

on (release) {

no probleme there.

In my movie1.swf I have a botton with the actionscript:
on (release) {
printNum(_root.printMc, “bmax”);

This botton print my printMc when I played my movie1.swf
but if I load movie1.swf in main.swf, it does not print my printMc.

If I load my movie1.swf in my main.swf in level0 it worked but I loose my design of course.

What to do…
