Bob,

This generates an error. The "Tab 1" after the 3 commas is highlighted. I am
using XL2000.

Here is one way

=SUM(OFFSET('Tab 1'!I7,,,'Tab 1'!COUNTA(I:I)-'Tab 1'!COUNTA(I1:I6)))

I have to build a workbook where columns of data will be cut and pasted
into
Tab 1, then the column totals need to appear automatically on Tab 2. The
problem is that the number of rows of data in Tab 1 will be variable and
unpredictable, although the columns will always start in a known row.

I might be able to do it by something like

=SUM('Tab 1'!I7:I65535)

but is there a more precise way?
