Validating Custom Item Required Responses

[Trevor Newell]

[edited from support email]

I have a question about how we can go about requiring a response on a custom items with multiple radio buttons. We have two forms of this nature, each with multiple radio buttons. In the first form, MediaLab will continue returning to the form if at least one item is not checked. What we would like is for MediaLab to display an error message indicating that the form is required, not simply loop back to the form without any correcting feedback.

In the second form, subjects could continue without selecting any radio buttons and it will move on to the next form. I'd like to make the form required in some way, even if it's only for a single radio button on the form.

Any advice on how to accomplish this?
