how do I just do basic record
navigation...can it be done without
paging...when I hit the buttons, the
asp page reloads/executes the original
SQL so my NEXT button will always give
you the second record...I can't get it
to stop reloading and resetting itself
to the first record...help.

I have next and prev buttons on a form,
having trouble navigating through a
recordset - the page reloads eachtime
and resets the form so that NEXT will
always give you the second record - can
I get around this without paging each
record...( I hope so...) Thanks.
