Here's my situation:
I'm planning building a new Flare project. It will have about 100 topics with links to training videos. Each training video link has duration info (mm:ss) tied to it. The topics will have multiple TOCs associated with them, each one creating a subset of the training material based on an end user's job duties.
I'd like to sum up all of these durations and put it at the beginning of the document so people know how much video time they can expect. Is there a way to do that (sum function on a UDV or something like that)? I'd like to do it in both printed and online output, but printed is my biggest concern.
