Hi Timothy,
I think the problem has to do with the fact that the glossary Excel report makes a distinction between glossary entries and dictionary entries. Glossary entries are those that don't have any Fields defined (note, these are fields that you see in the Fields tab along the bottom, not custom fields defined in the tools menu). Try changing the $listGlossary to a $listDictionary and let me know if that solves the problem. If not, we'll need to dig a little deeper to figure out what's going on.
