[AccessD] Friday Puzzler - Access 2007 – Report View – Dynamic Sort options are grayed out

This seems strange.

New small test table, new query, new report.

We open up the report in “Report View”.  If we right-click on a data field
we receive a Pop-up which allows us to use filters.  However the options for
Sorting are grayed out.

What are we missing?

Thanks,

Brad
