Caldera Star Element Conditional Logic

Using the Caldera Form Plugin:

I have a need for a feedback form where if someone leaves a rating of 4-5 stars they are re-directed to a ‘positive experience’ webpage, but if they leave a rating of less than 4 stars they are re-directed to a ‘negative experience’ webpage.

I am able to handle this using radio buttons but I would like to know how I would go about using the Star Element with the conditional redirects.

Under Form Processors under Redirect I have “if *Star element* is less than 4 and the settings are set up to redirect then to the negative page.

This is not working for me. What values do I use for the stars? Is it 1 to 5 or something else?

Thank you,
Patrick
