Thanks for the reply Christopher.
I did have it set up dictionary style, and I even tried a few of the other settings just to see if that would change anything, and regardless of the format, all 337 entries are under 'A'. So I just have it set to show 'ALL' rather than the A-Z. It kind of sucks, but it's better than nothing.
When I imported the glossary, I used the import2.php mod and uploaded a .txt file with the concept & definitions defined (not xml, just plain text, moodle formatting, not categorized.) It didn't say anything about defining anything else, so I thought maybe that's where I screwed up, I didn't define the alphabet somehow.
Thanks again,
Christine
