I have a 'Participant ID' field that references a csv list of unique codes that will be sent to individuals to complete the survey. I entered my pulldata formula in the Constraint field for the Part_ID field, and it works flawlessly in Survey123 Connect. But when I publish to webform (which is how the survey will be accessed), values that match the ID's still return a constraint error.
I've attached the Survey, the ID.csv, and a screen grab of the webform error. Thanks for any help!
Thanks for your help Scott. The validation is working well!
