The following is the code I have used to update the data from Zoho Creator to Zoho reports, unfortunately it is not updating the records. And no error is generated at the creator screen. 

I just want to update one record based on date criteria. 

rowInfo = map();

rowInfo.put("Date", input.Date_field);

rowInfo.put("NewDaily", input.New_Cars_Daily_Sales);

rowInfo.put("UsedDaily", input.Used_Cars_Daily_Sales);

rowInfo.put("WholesaleDaily", input.Wholesale_Daily_Sales);

criteria = " \"Date\" =' " + input.Date_field + " ' " ;

mapResponse = zoho.reports.updatedata("Sales Data", "Sales Table", rowInfo, criteria);

Thanks
