Transitions Between External SWFs

I have a similar problem to a recent post, but cannot seem to figure it out.

i want to have the buttons, which are actually movie clips, placed in the main.swf, which is loaded by the index.swf. the buttons then call the swfs to be loaded.

i’ve changed the “_parent.container” scripts, but nothing is happening. could anyone take a look at it and tell me where i’m going wrong?

i’ve attatched the files that i have so far.

thanks.
