Actually, you can use the Conditional Formatting dialog box to format the
combobox based on the selected value, as well as the AfterUpdate event, but I
suspect that Doug is corrrect in saying that she wants different rows to be
different colors.
I saw a post by Stephen Lebans adressing this a few years ago, in which he
said that it couldn't be done. If I remember correctly, his suggestion was
using a stripped down Continuous Form, doing the Conditional Formatting, then
using it as a subform, so that it appears as a Listbox, with the rows colored
appropriately. You could then use the click event to emulate the action of a
listbox.
