I'm new to using Creator and am confused about how to accomplish something.  I have created a call-tracking form that fetches contact records from Zoho CRM.  I can't figure out how to auto-update the next field, which is the customer's account number; this is a field in CRM.  Does anyone know how this can be done?  I have checked different help articles and am still confused.

Any insight would be greatly appreciated.
