I'm trying to create a formula field in a Aplication. In this formula field I want to get de CONTACTID field of a record. To get this I use zoho.crm.searchRecordsByPDC("Contacts", "email", Email).get(0). Doing this I obtain the complete record but I only want the CONTACTID field. What can i do to get this?

I tried to do: zoho.crm.searchRecordsByPDC("Contacts", "email", Email).get(0).get("CONTACTID") but It does not work.

Thanks,

Roberto
