Hi,

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:
=ISERR(R1) or =ISERROR(R1) or if the error is NA then =ISNA(R1)
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
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:
=ISERR(R1) or =ISERROR(R1) or if the error is NA then =ISNA(R1)
5. Click the Format button and choose a format.
6. Click OK twice

If this helps, please click the Yes button.

Cheers,
Shane Devenshire

If possible, I'd like to use conditional formatting to shade any cell
in Column R in which the formula in that cell returns an error. Can
this be done?
