If you are assigned to a visit which has a form/survey assigned to it, when you click into the visit you will find a green "View Surveys" button below the "Check In" and "Check Out" buttons. Click on this button to view all available surveys that are applicable to this visit.
Once "View Surveys" has been pressed you will be taken to the list of service that have been assigned to this visit. Select the service that you want to complete the survey for, by tapping the name of the service.
This will bring you to the survey response page where you can input answers for the questions. The way in which you answer will depend on how the surveys have been set up. Once you have completed all of the required questions, complete the survey by pressing the green "Submit Survey" button at the bottom.
When you submit a form, a 'tick' will appear next to the survey that you have completed. If you complete the survey multiple times, a number will appear next to the 'tick' to represent the amount of times the survey has been submitted.
