No, I want that message to appear if a person has put in a value other than yes, no, or blank, to tell them to do so. If none of the episodes have yes beside them (so they have either no or blank), then I want to have the line "No appearances in Series 1" appear in the space where the links to the episodes would have appeared if any of the values were yes.
