Ghosts in Multiselect listbox

1
I've got a form that uses a multiselect listbox. When a user is selected from a combo box, values are populated into this listbox associated with that user.

The problem is, if one person has say 10 entries in the listbox, and selects the last 3-4, and the next user only has 2 entries, those last 3-4 rows are still highlighted in the listbox. This introduces null values into my code which is definitely not good.

I've tried using beforeupdate and onclick events for the combo box - but they don't seem to execute at the right time (before the new information is loaded). Does anyone have any ideas for me?

(No, Exorcisms are not an option)

Thanks :)

If that doesn't work put it before the code that requeries the listbox which I assume is in the comboboxes after upate event.
