Hope this query makes sense - my first post..

I'm using Word2003 mail merge to add address block into
standard letters. Data source is Excel 2003 XLS, & I'm
using "advanced" filter facility within mail merge.

At step 3 of 6, I browse to correct tab within XLS and
all data is displayed correctly. I then select "advanced"
filtering in column headings, because I want selection:
col A = "N" AND col B = blank AND col C = not blank.

Data is filtered correctly, so I press OK and carry on
with mail merge. At step 5 I find that too many records
have been selected because the filter table has been
corrupted - for example it now says col B = blank AND col
B = not blank, so it selects nearly all records!

Any suggestions? My only workaround suggestion is to use
Excel to do the filtering, then copy the filtered data to
another tab and merge without using the WORD2003 filters.

Any other ideas? I'll be very grateful for any
suggestions.
