i'm trying to create a button that will replace the current swf with another
and i need to change the sizes between the various sizes of each page. i'm
currently using the following code in the action inspector:

on(release){loadMovieNum("myfilename.swf",0);
}

i know there has to be a simple way to do this! a very grateful thanks to
anyone who tries to help!

once you execute code that loads into _level0, there's no other code that will
execute in the swf that contains that loadMovieNum() statement.

so, you'll either need to load into a different _level, load into a target
movieclip or put code in the external swf (myfilename.swf).
