post variable to a page in process.php script?

[Jason]

I have an update form update.php that updates entries in a mysql db. On submit entries are updated using a php script in a file called process.php i would like the process.php script to redirect to a page called results.php but i need a $value from update.php to be passed to results.php. iv got no idea. ive used header('Location: but im stuck with the $value bit. (sorry for the confusion!) any help would be appreciated-
