Hi,
The formula you use depends on your definition of 90 days or less. Unless
you are looking for date within the past OR future 90 days you may need a
different approach.
To conditionally format your cell(s):
In 2003:
1. Select the cells you want to format
2. Choose Format, Conditional Formatting
3. Choose Formula is from the first drop down
4. In the second box enter the formula:
=AND(TODAY()+90-D2<=90,TODAY()+90-D2>0)
5. Click the Format button
6. Choose a color on the Patterns tab (or any available option)
7. Click OK twice.
In 2007:
1. Highlight all the cells on the rows you want formatted, in your case D2
55
2. Choose Home, Conditional Formatting, New Rule
3. Choose Use a formula to determine which cell to format
4. In the Format values where this formula is true enter the following
formula:
=AND(TODAY()+90-D2<=90,TODAY()+90-D2>0)
5. Click the Format button and choose a format.
6. Click OK twice
