Hi,
If you are really trying to hide the contents of B1 in B1 then you would not
want to set up the formulas in another cell.
If you were using 2007 you could use a different approach but in 97 I
believe the following will work. I don't have 97 on my machines on 2000,
2002, 2003, 2007 (and 2004, 2008 on the mac).
1. Select cell B1 and set the font color to match the background, most
likely white.
2. With B1 selected choose Format, Conditional Formatting and pick Formula
is from the first drop down.
3. In the second box enter the formula
=AND($A1="",$B1>0)
4. Click the Format button and on the Font tab set the Font Color to Black.
5. Click OK twice.
