How to update a form with data from a crm look up field in another form in the same application so that it shows as a text value rather than the ID number?

How to update a form with data from a crm look up field in another form in the same application so that it shows as a text value rather than the ID number?

Hi there,

I need to create  update a form called "US Customers" with data from a form called "Customer Cancellation Form".

This works fine using the Data Access/Add Record /"insert into... procedure . The only problem is that one field I need called "Organisation name" is a look up field to zoho crm . This field in the new form  displays the Organisation ID not the name of the organisation

insert into US_Customer
  [
      Organisation_Name=input.Organisation_Name
      Contact=input.Contact
      Email=input.Email
      Phone_Number=input.Phone_Number
      Address_1=input.Address_1
      City=input.City
      State_County=input.State_County
      Zip_Postcode=input.Zip_Postcode
]

I have  tried replacing line 1  with 
Organisation_Name=zoho.crm.getRecordById("Accounts",input.Organisation_Name.toLong()).get(Organisation_Name)
 but this just creates a blank entry for the Organisation Name in the US Customers form.

can someone help please?

Thanks 

Susan
