I have a combobox on an insert form which contains a list of staff members and their ID's.

e.g
Paul : 1
Anna: 2
Jules: 3

This all works fine until the user goes to the Update page. The update page contains the same combobox with the same list of staff members. The problem I am having is that if the user chooses "Anna" from the combo on the insert page.........on the update page "Paul" is always displayed because "Paul" is the first entry in the combo.

How can I get the update page to display the member of staff in the combobox relating to the contents of the underlying field which in the case of "Anna" will be "2" ?

Thanks in Advance
