CRM Custom Function - Change Quote Subject to include Quote Number

I created the following custom function, to maintain naming conventions in the Quote Subject and more importantly to include the Quote number in the Subject, which doesn't exist until the Quote is Saved (created). I thought I had it, but the Quote number included in the Subject is alway a number 2 less than the actual Quote number.

Any help would be appreciated!!

      QuoteId_String = input.QuoteId.toString() ;

 
      DateString = zoho.currentdate ;

 
      New_Name = ((((input.AccountName) + " ") + DateString) + " ") + QuoteId_String ;

 
      resp  =  zoho.crm.updateRecord(  "Quotes" ,  QuoteId_String ,  { "Subject" : New_Name } ) ;
