I am trying to pull data from our CRM to my application. Creator recoginises the records with out an issue but the code on the tutorial gives me an error. Please help

 te code recommended is 

crmResp = zoho.crm.getRecordById(“Products”, input.Product_ID);

input.Unit_Price = (crmResp.get(“Unit Price”)).toDecimal();

input.Quantity_Available = (crmResp.get(“Qty in Stock”)).toLong(); 

but the error is 

Error at line number : 1

Improper Statement

Error might be due to missing ';' at end of the line or incomplete expression

Any clues?
