nex/previous

Hi,

i have the simple form for user to enter in PurNo.  Results is displayed fine with next and previous navigation.  without order by from the query, the next/previous worked fine.  However, afer i added  order by PurNo, NesID into my query then navigation didn't work as expected.  for example, when i click next, i see it changed for message and date added column but not for Pur No.  Can any one tell me what's wrong ?

Thanks
