# MAX function doesn't like N/A!

I've got a column in which each cell has a formula linking to a different worksheet.

The cells can either display a positive number (not 0) or N/A

Row 2 of each column has: (in this example for column B)

=MAX(B3:B10000) (10000 to allow it to automatically update as new rows are added)

But because some cells have N/A, MAX also displays #N/A rather than just ignoring them and displaying the largest integer in the column.

Any way round this?

Thanks
Hugh

### Excel Facts

What is =ROMAN(40) in Excel?
The Roman numeral for 40 is XL. Bill "MrExcel" Jelen's 40th book was called MrExcel XL.
You can get rid of the #N/A values by using the IIF(ISERR formula....

I picked the following code up that you can run per worksheet to add the IF(ISERR string around your formulas.

Code:
``````Sub ErrorTrapAddDDL()

' Adds =If(IsError(xxx)) around formulas
' results in no error values on speadsheet

Dim cel As Range
Dim rng As Range
Dim Check As String

Const Equ As String = "=IF(ISERROR(_x) ,"""", _x)"

Check = Left\$(Equ, 12) & "*" ' Check for =IF(ISERROR(

On Error Resume Next

Set rng = Selection.SpecialCells(xlFormulas, 23)
If rng Is Nothing Then Exit Sub

With WorksheetFunction
For Each cel In rng
If Not cel.Formula Like Check Then
cel.Formula = .Substitute(Equ, "_x", Mid\$(cel.Formula, 2))
End If
Next
End With
End Sub``````

Hope this helps

Try to avoid #N/A. You could generate "NoValue" instead of #N/A, for example.

Having said that, you can use the following array formula in case you keep #N/A's:

=MAX(IF(ISNUMBER(\$B\$3:\$B\$10000),\$B\$3:\$B\$10000))

To array-enter a formula, you need to hit control+shift+enter at the same time.

If you switch to "NoValue", you can just use

=MAX(\$B\$3:\$B\$10000)
