Populate a dropdown with data from another Zoho Module

Populate a dropdown with data from another Zoho Module

Hello, 

I'm quite a newbie with Zoho Creator but I have a simple use case which I can't succesfully achieve. 

My request is quite simple. I would like to populate in my application a dropdown with data from another Zoho Module. Actually the list of vendors which are hosted in Zoho Books. 

The steps I've followed are the following: 
1) Creation of the Zoho Creator / Zoho Books connection 
2) Setup of a workflow (On Load of Form) with the following Deluge code:
  1. response = zoho.books.getRecords("Vendors","20085118368","","booksconnection");
  2. info response;



When checking the log details from the application side, here's what I get. 



So step by step, I would like to understand the following:
1) How can I filter in the Deluge script to only retrieve Vendor Name
2) How can I populate a dropdown with those Vendor names. 

Thanks in advance for your help. 

Mark
