contolling several external swfs with one button

hello,
i have a navigation on level0. from this i control via buttons several external swfs. i want to control with i.e. button2 two swfs to play one after another in the following way: 1.swf should go to frame2 and when finishing playing, 2.swf should start playing.
what i have now is:

code:

---

on (release) {

    _level1.gotoAndPlay(2);

    _root.ladefilm = "1.swf";

}

---

this is for playing 1.swf frame2. but what do i have to tell my button when i want 2.swf play afterwards?
someone got an idea?

at the last frame of 1.swf give code to load ur 2.swf

Its possibly slightly more complicated than that as there might be variables to take into account.

the problem might be that i have a navigation with at least 15 items. so if i have 1.swf loaded and tell him in the last frame to load 2.swf that might work but how should this work with e.g. swf.15?
it's really a bit more complicated...what it all boils down to is the following: i want smooth transitions between the single swfs. so if i have 1.swf and click button15 to load 15.swf there should be played some transition-part before 15.swf shows up.
you can see what i mean when you visit

e.g. the 'bedroom' items...there is what i mean. wonderful smooth transitions between the movies.
any idea how to do this? maybe this won't even work with external swfs?
