Hi, new to Nintex, and have time pressures.  Just trying to work out how to auto populate a choice field based on another choice field.    I found the how-to guide that explains how to auto populate a single line of text field but the "set value" option is missing for a destination choice field.

Somewhere else I read that I'd need JS, but this is only for classic forms only ....  Is this seemingly standard requirement not available for a response form?  Is there a way to convert the a responsive form to classic?
