Find most recent value in data range that includes SUM formulas

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?
 
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.
 
It should work. It doesn't make a difference whether the values are
constants or the results of formulas. As long as the values are *numeric
numbers* the formula should work.
 
Now it reports "#NA" if the value is zero, but correctly if there are values
to be summed. How can I get it to report 0 if there isn't a value to report?
 
Try this:

=IF(COUNT('Worksheet reference'!O12:X12),LOOKUP(1E100,'Worksheet
reference'!O12:X12),"")
