Require questionnaire sequence
This feature is only included in the Enterprise plan with option Campaigns.
You can require respondents to take the questionnaires in the order that they are presented. They will only gain access to the second questionnaire when they have completed the first one. You can only use this feature when you attach your respondents to the campaign up front (learn more here).
Within your campaign, click on the Extra options tab.
Turn on require questionnaire sequence.
That's it! Log in and try it yourself!
