    NULL Reference exception means that the you are trying to use an object's value without initialising it.

    You should debug to the point where this error occurs and should check the nullness of the object before accessing the value of object like:

    if (object != null)

    {

         // Access object's value

    }

    else

    {

       // Object is NULL

    }
