Creating a simple loop

I created ten poorly drawn circles that, when played in succession, look like that wavering animation that George Plympton (I think) made popular.

Anyway, all I want to do is loop it, so it goes on forever. Yet, this simple skill evades me.

I have put all ten images into Comp 1, and then nested it into Comp 2. I added a "Time Remap" and then tried to loop it by adding the expressions "loopIn ("cycle",0)" or "loopOut ("cycle",0)". [Not at the same time.]

Anyway, nothing seems to be happening.

Any help? Thanks,

Mike
