As per your query , you have problem in the above line. What you have written is bound to get an error like that. Because, "obj" is a reference to a control. And as control does not have substring method in javascript you get this error. You should call obj.innerText or obj.value which ever is applicable in your case( depending upon what the control is rendered in your browser for your code) then call the substring method.
