James Can u give me some suggestion on the approach I should take, I was able to at least come to this stage after 2 weeks of struggle. Now I have some idea as how these tags work, if u can provide me alternate approach it would be great.
Thanks >>> [EMAIL PROTECTED] 06/11/03 05:16PM >>> I don't recommend doing it this way, but the problem seems to be with your last select tag. The previous ones had an index, the last on does not.
