Tip 30: Avoiding Error Displays in Formulas

Sometimes a formula returns an error, such as #REF! or #DIV/0!. Usually, you want to know when a formula error occurs so you can fix it. But in some cases, you might prefer to simply avoid displaying the error messages. Figure 30-1 shows an example.

Figure 30-1: The formulas in column D display an error if the data is missing.

Column D contains formulas that calculate the average sales volume. For example, cell D2 contains this formula:

`=B2/C2`

This function takes two arguments: The first argument is the expression that’s checked for an error, and the second is the value to return if the formula evaluates to an error.

The formula presented earlier can be rewritten as

`=IFERROR(B2/C2,”...`
