Loop possible?

Hi,
(using flash 8)
(if a solution has been posted previous please point me there)

I have a problem with looping text-tweens.
this might be trivial or not.

the setup is:
I have 3 channels each containing 3 sets of different words fading in and out.
At start only one is visible, then text starts on second channel
and then 3rd. The problem arises when i want these text-tweens to
loop forever and seamless. As it is now channel 1 fades out and then not until 2&3 fades out
channel 1 appears again and it starts over. I want it to start looping already when
channel 1 fades out.

How do I do it? as it is now all tween frames
are in the channel and not as movieclips.
where do i go from now?

All help appritiated
