    Hello Jason Ching,

    I tried to access the rows collection as you are doing it and it seems to work fine for me with versions 8.1 and 11.1 of Net Advantage. Could you please test your application against the latest service release available for you and see if this behavior is still occuring.

    Please do not hesitate to ask if something comes up.
