If you apply your filter (filtering by that value--not just putting the arrows
in place) once more, look at the row numbers to the left.

The row numbers that are part of the autofilter range are blue. If the row
numbers are still gray, then they weren't part of your autofilter range.

Remove the filter arrows
Data|Filter|autofilter
then select your range--don't let excel guess
and reapply data|filter|autofilter

Then test it out.

I have a worksheet with about 5,000 lines. When I try to autofilter on a
selected item from the dropdown menu, it displays many more cells that don't
contain that value (including blank cells) and indicates only 1 line was
found. I've never encountered this problem before with autofilter.

BTW, in case it means anything, the workbook was originally a shared
workbook. I "unshared" it before applying the autofilter. And, I did try to
copy and paste special, values only, into a new workbook. Same problem and
results.

Any thoughts from anyone? Thanks in advance.
