I don't have the time to think this through but I recently had a
similar problem and got help from this list. Here is what I ended up
doing using arrayjob:
In a stylesheet called RAFv3-0_CheckableItems, I enter the data, e.g.
"alpha", "beta", "gamma", etc:
-%this is an empty cell
Then, in the document I have
which automatically shows alpha, beta, gamma, where it should. It
makes things reasonably foolproof.
I hope this is comprehensible but, if not, I can send the complete
files off list to anyone interested.
