We are using gravity forms with the GravityPlus connector to Salesforce. For new customers, this is working perfectly. For returning customers I cannot figure out how to get the account ID from the salesforce record to populate onto the form submission and case to then have the new information process into salesforce attached to the appropriate account. we are using person account.
So for example, all made up Mary Smith DOB 1/1/1901 is an existing customer so I need gravity forms to find her in salesforce then pull back the Account__C or Account__c1 and then populate that field on the gravity form so when the next salesforce feeds run it is on those feeds.
