Filtering specific data within a custom report
I've recently created a custom report on survey's that were sent to my employees, however I have to somehow separate (possibly by using a filter) the surveys that have been completed along with the surveys that have NOT been completed. I'm not quite sure how to set this up. I did add a field called "Rating" within the report that does give me not assigned, if they have not taken it, however below that it is showing the rating numbers. I'd prefer to have that instead say "completed" or "assigned". Please, any input would be appreciated.
