You can insert a cell error value into a cell or test the value of a cell for an error value by using the CVErr function. The cell error values can be one of the following XlCVError constants.

Constant Error number Cell error value
xlErrDiv0 2007 #DIV/0!
xlErrNA 2042 #N/A
xlErrName 2029 #NAME?
xlErrNull 2000 #NULL!
xlErrNum 2036 #NUM!
xlErrRef 2023 #REF!
xlErrValue 2015 #VALUE!

Example

This example inserts the seven cell error values into cells A1:A7 on Sheet1. 

myArray = Array(xlErrDiv0, xlErrNA, xlErrName, xlErrNull, _ xlErrNum, xlErrRef, xlErrValue) For i = 1 To 7 Worksheets("Sheet1").Cells(i, 1).Value = CVErr(myArray(i - 1)) Next i

This example displays a message if the active cell on Sheet1 contains a cell error value. You can use this example as a framework for a cell-error-value error handler. 

Worksheets("Sheet1").Activate If IsError(ActiveCell.Value) Then errval = ActiveCell.Value Select Case errval Case CVErr(xlErrDiv0) MsgBox "#DIV/0! error" Case CVErr(xlErrNA) MsgBox "#N/A error" Case CVErr(xlErrName) MsgBox "#NAME? error" Case CVErr(xlErrNull) MsgBox "#NULL! error" Case CVErr(xlErrNum) MsgBox "#NUM! error" Case CVErr(xlErrRef) MsgBox "#REF! error" Case CVErr(xlErrValue) MsgBox "#VALUE! error" Case Else MsgBox "This should never happen!!" End Select End If
