Thanks. I fixed the problem. Was connected to different language code for
date appearance on windows and excel level.

One reason could be that you don't have real dates in your column -- you
have text. Try using =isnumber to find out.

Post back with examples if you need more help.

I created a table with "date" and "name" being some of its columns.
Unfortunetly when I filter it by name and want to customize a filter for
the
dates afterwards it doesn't work. For example if I want to see all rows
for
July by customizing the filter with the greater respectively with the less
than criteria, then it doesn't show me a single row from July. What might
be
the reason for that?
