[AccessD] Select Value in ListBox

Hello All,

I have a form that displays data for an individual...Individual_ID.  I want 
to print a report for this Individual_ID, but allow the user to include 
other Individual_IDs in the report...from my printing form I have a 
listbox...which my report uses as criteria.  My problem is I want the 
listbox to automatically select the Individual_ID from my first form.  I 
already have the listbox and report working fine...I just can't get this 
'default' selection in my listbox.  I think I'm looking for the ItemData# of 
the Individual_ID...but not sure how to get it?

Thanks,

Mark A. Matte
