"I am conducting research to monitor the depression status of patients. It's crucial that I track their status on a weekly basis. Consequently, I am looking to set up a reminder calendar to facilitate this. I've utilized the provided formula to determine follow-up dates, but Airtable suggests that the outcome isn't recognized as a date format. This has hindered my efforts to create a calendar using the results. I would greatly appreciate any advice on this matter. Thank you!"
