Hello,
I'm attempting to build out a question that asks UK respondents what their three digit postal code is. I have this currently constructed as an open-end numeric: min 001, max 999; response not required. I would also like to have a single radio button underneath that allows respondents to select 'prefer not to answer'.
I'm having trouble writing Javascript that forces respondents to either enter a three digit numeric response in the open-end field or select 'prefer not to answer', but not both.
Any help with this would be greatly appreciated.
Thank you!
