I had them backwards used sheetb for sheet1, and sheeta for sheetb
but it seems more like you want to use a filter, in which case you
only need one sheet.
If you are trying to display only rows in sheet2 that have an "M"
in Column H then you would filter on Column H for a value of "M"
Select column H then
pref Excel 2007 Data, Filter, on the drop down on row 1 choose "H"
in Excel 2007 (forget it but it is)
Data, Filter, on the drop down on row 1 choose "H"
So much for that, can't stand Excel 2007
You can copy a filtered list and paste is elsewhere as if
the filtered out (unshown) columns aren't even there.
Same for using a filtered list for Mail Merge in MS Word
using a filtered list in Excel as the database.
Debra Dalgleish has pages on Filtering, is that is the type
of thing you want.
