SYMPTOMS
When you cancel a dialog box displayed with the InputBox method in Microsoft Visual Basic for Applications, you may receive the following error message:

Runtime Error '424'

Object required



CAUSE
This error message occurs when all of the following conditions are true:

 You create an object variable.

-and-  You assign the variable using InputBox as in the following example:

Set myRange = Application.InputBox(Title:="Count Columns", _  Prompt:="Select range to count number of columns.", Type:=8)

-and-  You click Cancel in the dialog box displayed by InputBox.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

To successfully trap the value returned by clicking Cancel, you need to add error handling to your code. The following is an example of error handling that you can use with the InputBox method, to prevent the error message described in this article.

 Start Excel and create a new workbook. 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>
