At present this is working the wrong way around.
The display is the ID and the link is the text?
i.e. if you had a client called fred with an id of 1234 and set tghis as a hyperlink tnen you'd see "1234" as the field (not fred) and the link would be (e.g.) Client_view.php?editid1=fred rather than Client_view.php?editid1=1234
