If you have blank rows in your data, and you let excel guess what range should
be filtered, you may see this problem.

I'd remove the data|filter|autofilter
Then select the complete range
and reapply data|filter|autofilter.

I have been building an Excel 2002 spreadsheet here at work. I have a total
of 6781 lines and my columns are up to "Y" . My problem is that any of my
entries past line 6726 will not filter out when I use any of the column
filters. Everything sorts in fine. Is there any limits to this version?

Thank you,
Curtis
