Offset last cell

Hi,

I would like to sum last three cells from column use offset formula?

Best regards

What have you tried so far? Documentation: OFFSET. Include an example.

yes i use offset for three cells but i would like to change that to have last three cells not first one

=SUM(OFFSET(Maps.C1;3;0;3;1))

Do you mean the three cells above the reference (this is done using negative values) or the last three cells of an unknown reference? (a.k.a. Maps.C1 is a single reference with an unknown number of rows following?)

Thank you!, you help me with your question! I need to set up offset to sum last not empty three cell in column. So now i know i can change reference to last one and give negative number. Thank you! You can give it as a answer and i gonna give you karma.
