I've got a form with a radio group called 'legal_status'. There are five radio buttons. The last one has an id='other_radio'. If this button is selected, I have a textarea field that gets displayed. The field has an id='legal_status_comment'. This textarea field is wrapped by a div with an id='other_text_area' that is hidden until the other_radio button is selected.
How do I write the rule to make the 'legal_status_comment' field to be required if the 'other_radio' button has been selected? Thanks!
