How to handle validation on a combined Radio buttons and Textarea question?
I have a question with a Yes/No response. For example....
Any other comments Yes (value = 1) No (Value = 2)
Below this I have a textarea field. If the user selects Yes, I'd like validation to force them to complete the textarea.
What type of validation should I be selecting here? I couldn't see anything relevant.
I need to do the Validation If, and that needs to be based on the Radio button response, but I'm not clear what type of validation to run? Alphanumeric and only allow a 1 or 2?
Would appreciate your advice. Thank you.
