When retrieving information about a profile with CCProfileGetCustomer, CCProfileGetShipping, or CCProfileGetPayment, the response will return a list of values marked with a dollar sign, like so:
To parse out these values, you can use a combination of the Evaluate and Let functions. After seeing a response from the gateway, note the value you want to parse, such as $billingLastName in the example above. Then you can use the formula:
Evaluate ( "Let([" & Transaction::Response Message& "] ; $billingLastName)")
Which will return the last name of the profile requested.
