Write the latest value to "BookingStatusCP__c" if the form is submitted more than once during the same session. Here is an example. One of our prospects submitted a form at 10:45 and did not book a meeting. At 10.46, the form was submitted again by the same prospect, and this time meeting was booked. Chili Piper wrote to HubSpot "Booked" at 10:46 but it was updated to "Not Booked" at 10:50, which is the wrong status.
