When adding numbers to create a final value for the buttons argument, use only one number from each group.

§ When both HelpFile and Context are provided, the user can press F1 to view the Help topic corresponding to the context. Some host applications, for example, Microsoft Excel 2010, also automatically add a Help button to the dialog box.
§ If the dialog box displays a Cancel button, pressing the ESC key has the same effect as clicking Cancel. If the dialog box contains a Help button, context-sensitive Help is provided for the dialog box. However, no value is returned until one of the other buttons is clicked.
§ Note: to specify more than the first named argument, you MUST use MsgBox in an expression.
To omit some positional arguments, you MUST include the corresponding comma delimiter.
