I want to do a longitudinal survey and I have created two forms(parent and child project) The only data that I want to be linked to the child project from the parent project is the patient unique ID-See highlighted attached xls(The unique ID auto generates in the first instance when administering the parent project, The unique ID should be the same in the subsequent child projects which is why I want it linked). I have managed to load the parent project but unable to load the child project because of the error attached(also).
Please assist so that I can be able to load the child project and the auto generated patient id to be linked up to the child project
