Hello, as someone in this nice group suggested, I've created a pivot
taking data from a sheet in the same file.
Columns of my data a day (1,2,3...), bank account, name, company,
amount of money, reason.

The wonderful pivot shows everything in a wonderful way, having sum of
amounts of money ordered in any way I like...the things that I need it
to be able to use a cell of the pivot on another sheet.

An example: in the pivot I have a cell with the total expences of
march regarding Mr. Brown.

Now, I would like to create a simple sheet where I can re-use that
total for other reasons but that is not possible, for me, because the
link doesn't work (the cell position in a pivot change according to
the filtered data) and because I don't know how to get a formula for
that total.

Any help or solution? Maybe it is something very easy for you but I'm
worried because I need to re-use those data.

Thank you,
Ataru
