This is one of those subtle syntax problems. The third parameter in a
messagedlg must be an array. There are some predefined arrays such as
mbYesNoCancel, which are put in without brackets. You need something
other than a predefined array, so put them in as an array:
(...mtConfirmation, [mbYes, mbNo], 0)
Even if you want only one button, it must be in [brackets].

You must enclose mbYesNo in brackets [mbYesNo]
