A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Thanks very much for your replies.
While doing some more searching I found a suggestion to someone else's similar question; add a '<' before the '=' . So the new formula would look like this:
IF(W4-W3<=0,"",W4-W3)
Seems to work on the spreadsheet I'm working on. Haven't tried it on any other spreadsheets though. If anyone knows of a problem with doing a formula this way, please let me know.
Thanks again
