We can force your LOOKUP() to work!!

In O12 you may have something like:
=SUM(O1:O11)
replace it with:
=IF(SUM(O1:O11)=0,"",SUM(O1:O11)) and copy across

This way if the SUM() reports a zero, we make it a blank and your LOOKUP()
will be happy again.

I have a series of cells that sum the columns above them (O12:X12) on
multiple worksheets. I would like to write a formula to report the cell that
has a value and is the furthest to the right. I used:

=LOOKUP(10^10,'Worksheet reference'!O12:X12)

This worked on a previous worksheet when the data range contained values,
but since O12 through X12 include SUM formulas, it's not working.

Any ideas?
