Deluge and Books with line items

Deluge and Books with line items

I am trying to code a solution that looks at invoice line item in a workflow and if they contain certain products updates CRM module.
I have been slowly trying to learn deluge but am stuck.
I have managed to grab the invoice data and can pullout various elements as I need them but line items is only ever giving me the first item. Even when I created a loop. Have I missed something or more likely I am going at it the wrong way.
I would love a point in the correct direction please.

  1. invoiceId = invoice.get("invoice_id");
  2. organizationId = organization.get("organization_id");
  3. invoiceRecord = zoho.books.getRecordsByID("invoices",organizationId,invoiceId,"zohobooks").get("invoice");
  4. customerId = invoiceRecord.get("customer_id");
  5. dateIn = invoiceRecord.get("date");
  6. info customerId;
  7. info dateIn;
  8. info invoiceRecord;
  9. lineitem = invoiceRecord.toJSONlist();
  10. for each  product_json in lineitem
  11. {
  12. itemmap = lineitem.toMap();
  13. name = itemmap.get("line_items").getJson("name");
  14. //name2 = name.get(product_json);
  15. }
  16. info name;
  17. info product_json;
