I finally figured out this one with COUNTIF function (only because the valued
cells happen to be contiguous)...

My data are in two columns and look like this:
A B
50 6.53
51 6.53
52 6.56
53 0.00
54 0.00
55 0.00

How can I get the row index of the last cell in col B whose value0 (the
values can be in order, not necessarily descending)?

I looked at ROW, ROWS, INDEX, MATCH, MAX, etc. functions, but wasn't able to
put them together to get what I need. I hope this is possible w/o VBA...
