why is my Data tab disabled?

[llacher]

suddenly, I can't use any of the functions on the DATA tab in EXCEL 2007.
Does it have anything to do with the "group" designation attached to the file
name at the top of the worksheet?

Correct

Ungroup the sheets
Right click on a shet tab and choose Ungroup sheets

Thanks very much! Sometimes, it seems to fix itself if I wait long enough.
