Using SetInterval, to load different movieclips

Hello,

I am a total newbie scripter, but until this problem i was going quite happily with my task, well the scenario is that I'm showing several movieclips on the flash screen according to the user interactivity through buttons, now i have a task that i should show those movieclips on the screen on their own with some delays ...

I used setInterval method but it can run and stop the counting of numbers : ( , but could not load and unload the movie clip .....

All in short, that how can I Load several movieclips using setInterval method one by one, (when second loads the first vanishes {clearInterval}.....)


It is very urgent and i 'm badly mingled in this problem... please help ...

P.S. I'm using Flash MX 2004, so don't hesitate in giving help with latest functions ....
