sorry, was trying to edit my name out of the original post and don't see an edit button anywhere.

The Edit menu entry should be under the Question Tools group that you can expand via the arrow. I've removed you last name for now. You can remove your first name yourself or I can do that if you want.

Thanks cor-el and Pkshadow! Appreciate the quick response. Resolved.
