Sound Familiar? Clip plays 3 times

well, well.
I got me a movieclip that, in the old browser there, plays the first 3 times. Moves timelines nested within other timelines through movieclips, like a teenage mule.

Then, from outta dang near nowhere, the wee child timeline, she just up and quits on me. It seems like she’s stuck on frame 1, somehow.

I wonder if anyone has experienced this phenomenon in the past. If so, I sure would be much obliged to know how ya fixed her.

Thanks, now.
