Thanks, Mark! When I saw your post I thought, "Haven't I already tried that combination?", but then tried it again, and it worked perfectly.
I'm new to Xpages, and think I lost confidence and started flailing around early instead of just calming down and figuring out the elements.
SO MUCH BETTER than messing with the data... thanx mucho mucho for taking the time to work through it and respond.
