Error message is not customizable and localizable



When the same subscript is added on the SubScriptPromp error message appears. "subscript is not valid or is already in use" . That is expected behaviour but the error message is not customisable and localizable when the same subscript is added.

The main source is from a final rule SubscriptPrompt where the section SubscriptPromptInput is called. This is a final rule and does not accept any changes.
