Lip Sync in TBS4

Is there a tutorial somewhere on Lip Syncing for Dummies for TBS4? I’m trying to do a lip sync. I have a short sound clip (maybe 5 seconds). I have all the drawings for the lips. In fact, I’ve done this in TBS 3.5 with the same character, different sound file. I’m not getting anywhere with the Help system. I just end up with a character whose mouth doesn’t move. I think it must be something pretty basic that I’m missing or doing wrong, but haven’t been able to figure it out.

Figured it out. I was making the mouths separate drawings instead of all under the main drawing. And then naming the drawings “A” instead of "drawing-A."

Amazing the stuff you can forget when you don’t use something for a few months…
