I am creating an internal scheduling tool that names internal participants. The flow is built off of Microsoft Forms and populates a sharepoint list. The column i am trying to populate is required to be a person or group because i am pulling the phone number from office 365 account using a seperate flow. The issue is that i do not always need to know the person in question so it is not a required question. When it is not filled out, the form fails because it does not recognize the person. I am trying to write a formula that leaves the entry blank when the answer is blank and therefore does not error out the form.
every formula i enter comes back invalid.
