Zoho Survey to CRM integration not adding new leads

I have a survey set up to capture information from new leads as well as some returning visitors.  I integrated the survey before pushing it live and selected the Add/Update Record option.  I just checked the survey results and there are new users that have completed the survey but I cannot find a record in CRM for them.  The CRM integration has worked fine on other surveys I've created, please advise as to why this one isn't working.
