I have button associated with Quote related list in the Deals module. I want it to update the Quote Stage field in the Quotes module. I have found some script similar but cannot get it work. Any help would be appreciated. 

This is what I attempted to modify but i am not versed in Deluge script.

potIdStr = input.potId.toString();

mp=map();

mp.put(“Quote Stage”,”Sent to Invoicing”);

update = zoho.crm._updateRecord(“Quotes”,quoteIdStr,mp);

info mp;

info update ;

return "success";
