How can I make iWork Numbers not show me negative results?

For example: The thing is that in A1 I have number 101 and I am doing -A1 from B1. B1 is empty (because I am waiting for the result) so in C1 (which is the result of the A1/B1 calculation) it is showing me -101.

I dont want to see any result in C1 before I receive the missing result from B1.

Can you maybe show a screenshot or something? I'm not sure I'm fully getting this. – slhck Jun 16 '11 at 22:48
How can I send you the screenshot?? – Mikel Jun 16 '11 at 23:16
NOW SHOWING B1(empty) - A1(101)= -101 – Mikel Jun 16 '11 at 23:40
empty-101= -101 I WANT: empty-101=empty or empty-101= 0 Finisht: 110-101=9 – Mikel Jun 16 '11 at 23:43

This answer disregards the fact that the result is negative, but it will not show you a result if the conditions are not correct.

For the sake of clarity, if formala in B4 is `=IF(B3="","",B2-B3)

The after shot (when B3 has a value) looks like this:

This is from Numbers 09.

FWIW, that is the same formula I would have used in Excel. I'm glad it helped. – Kirk Jun 17 '11 at 1:34
