Press ALT+F11 to open the Visual Basic Editor.</li>  On the Insert menu, click Module and type the following code in the new module: Sub CountColumns ' Dimension myRange variable. Dim myRange As Object ' Begin error trapping. On Error GoTo ErrHandler ' Store InputBox value into variable myRange. Set myRange = Application.InputBox(Title:= "Count Columns", _ Prompt:="Select range to count number of columns.", Type:=8) ' Show message box. MsgBox myRange.Columns.Count ' End macro. End ' Show message box when Cancel is clicked or other error ' is encountered. ErrHandler: MsgBox "No columns selected." End Sub </li></ol>
