One time I had a similar problem and solved it by using a very small number,
like .00001 instead of a zero. With the proper formatting, the display still
looks like a zero, and the small number does not materially affect any math
done to the numbers...........or, you could always but an X in those cells to
show acknowledgement of "No Production".

I have a spreadsheet I use to track production of a given facility. Some
facility's production is zero. I want to make a distinction between zero
production and a blank cell. Is this possible? I run a conditional format
to tell me when data is missing, however it sees the zero values the same as
a blank cell.
