The error reads: The are at least two Radio Buttons which have the same value. Since the gorup is meant to be mutually exclusive, all values must be unique.
I've tried using the object pane to rename but it doesn't remove the warning.
Try going to the binding tab of the object palette, and in the grid under "Specify Item Values" check all the values in the "Value" column are unique, if not you can double click that row and update the value.
