If you want to enter data into surveys manually (e.g. if you have collected survey data on paper), then you can do the following:

1. Create the survey forms in Castor.
2. Create survey invitations in bulk or per record.
   • You can choose to enter your own email address, as creating survey invitations requires an email address.
   • For the 'Send on date', choose 'Decide later', so that the surveys are not sent.
3. Navigate to the Surveys tab.
4. Click on the cogwheel of a survey, then click 'Open survey in new window'.
5. Transfer your data from the paper survey to Castor.

It is not possible to enter 'missing' data in surveys, like it is for study forms and repeating data structure.

You can also print the surveys for survey completion on site or at home.
