Field type "Name" how to input/parsed to the "First Name" & "Last Name" part

Field type "Name" how to input/parsed to the "First Name" & "Last Name" part

Zoho Creator has field type "Name" which consists of 'First Name' & 'Last Name'

If pulling a first name and the last name of a contact from CRM related contact, how can this be input/parsed to the Zoho Creator 'Name' field?

Here is an example of the deluge code im trying to correct:

potIdStr = input.Potential;  //***Working
crmRelat = zoho.crm.getRelatedRecords("Contacts","Potentials",potIdStr); //***Working
input.Email = crmRelat.getJSON("Email"); //***Working
input.Name[First Name] = crmRelat.getJSON("First Name"); //***this part not working [First Name]
input.Name[Last Name] = crmRelat.getJSON("Last Name"); //***this part not working [Last Name]
