This isn't going to help you much, but I've been trying this all morning, and I can't make the combobox show 2 decimals when the rowsource is an integer pk, and the form property is initialized to an integer. Not even if I set it to 'dropdown combo' and set the display format to '9.99'.

Are you sure there isn't something else in maybe the combo valid, or somewhere that is causing this?
