Refreshing your Analyse page pulls through any new responses and includes them in the Summary report. If your Analyse page does not appear to be displaying the correct number of responses, refreshing should resolve this.
Click Refresh data 
at the top right of the Analyse page to refresh the information. You can do this as many times as you like while the survey is open.
If the Refresh data link is not visible or does not work, please contact the online surveys support team for assistance.
