Ok, It sounded like you wanted to use the new updated value.
it would be helpful to have the entire page rather than just the update record code so I could see how the form action is set as well as the recordset.
I have a feeling the recordset is set to filter on a querystring variable that is not included as a part of the form action.
If that is the case, the url variable needs to be included with the form action:
action="updatepage?id=<?php echo(isset($_GET['id'])?$_GET['id']:""); ?>"
