How do I reference the last row and selected cell/s?

[Robert]

I have data in a dynamic database and require the total amount of
selected cell(s) on the last row to be displayed on another sheet.

I'm not sure if this is exactly what you want but here goes anyway...

If your database runs from say A1 to Z10000 with headings in row A

=OFFSET($A$1,COUNTA($A:$A)-1,0)

will return the value in the last row of column A whichever row it i
in. The same can be done for the other column

Thanks Alex, exactly what I wanted.
