Making Submovie preload itself

Hello Again.

I´m trying to use a preloader in the first scene of a submovie, loaded through a target in the mainmovie. The target is called: gästbok target

I’m using these commands calculate file size and bytes loaded.

iBytesTotal = “_root.gästbok target”.getBytesTotal();
iBytesLoaded = “_root.gästbok target”.getBytesLoaded();
iBytes = Math.round((iBytesLoaded/iBytesTotal)*100);

… and it does not work. I suspect there is something wrong with the way I tell these functions what to load?

Please help…
