Load next scene of imported swf at specific time

Hi I’m using actually using flash CS3 (not sure if this belongs in the actionscript forum?) and I have a movie file that loads into my main movie that displays a weekly event that I have to manually change every week. The imported movie contains a graphic that I change every week.

I use this to bring the movie in…

loadMovieNum("this_week.swf", 13);

What I would ideally like to do is have several weeks worth of graphics on sequential scenes and have the main movie automatically load the next scene of the imported swf at 5am on Sunday morning for a period of 1 week. Then change again the follwing week etc.

You can see the imported swf on the site here, its the date and name that flies in on the bottom right.

Hope that makes sense!

Thanks
