Preloading an external .swf

Hello. I have a question about the following tutorial below: http://www.kirupa.com/developer/mx/preloader_transition.htm#

I have everything working but this is my only issue. I have a LARGE .swf file that sits externally. It starts playing before the loader transition opens. Can anyone help me have the “loader transition” open after the external .swf file loads completely or after 30 seconds of downloading?

I’m pretty new to action script and VERY new to external .swf’s so if this is a “stupid” question I appologize in advance. Thanks

btw: I LOVE THIS SITE!!!
