Conditionally Displaying a Message Box

Written by Allen Wyatt (last updated July 18, 2026)

You may have a need to display a message box whenever specific information is placed in a specific cell by the user. Fortunately, using the Change event for a worksheet can help you to figure out when something has been placed in a cell.

For instance, let's say that you wanted to display a message whenever the information in cell C3 is changed. The following, added to the code window for a specific worksheet, will do the trick:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Address = "$C$3" Then
        MsgBox "Changed It!"
    End If
End Sub

The Change event is called and passes the cell range to the routine. In this case, the range is assigned to the Target variable. The address of this range is then checked, and if it is equal to C3 (it has to be noted in absolute terms, such as $C$3), then the message box is displayed.

Note:
