Select from list box into another this box and then insert into subform of under lying form

Hello

I'm developing this db in Access2003 but formatted in 2000 for the eventual end users.

In a form a want select items from a source list box and insert them into a destination list box with a cmd button.  Of course I will need additional cmd buttons to remove and clear the destination list box. Once all my selections are made I would click OK cmdbutton that will take the selected items and insert them as a new record(s) in a subform in an underlying main form.

Form: frmINCIDENT on table tblINCIDENT
      Subform: frmINCIDENTSUBJECTSsub on table tblSUBJECTS

Form: frmSUBJECTSSRCH unbound
      List Box: lstSubjectsSource
      List Box: lstSubjectsDest

This is what I got so far:

I have a single bound form called frmINCIDENT with a subform called frmINCIDENTSUBJECTSsub in datasheet view based on table called tblSUBJECTS.  The master and child links between the form and subform is called IncidentID

From frmINCIDENT I click on a cmdbutton that opens an unbound form called frmSUBJECTSSRCH.
In that form I have a list box called lstSubjectsSource that lists selected fields from tblSUBJECTS. The selected fields are SubjectRef, Surname, G1, G2 and DOB.

This is what I don't have:

I need cmdbuttons to select items from lstSubjectsSource and place copy them to another list box called lstSubjectsDest in the same form.  I also need cmdButtons to delete or clear all my selections

Once the selections are made I need a cmd button that will duplicate all the row fields of those selected items and insert  them as new rows into the the underlying subform frmINCIDENTSUBJECTsub in frmINCIDENT.  Finally the auto field IncidentID in frmINCIDENT needs to be linked to new records in the fields called IncidentID in frmINCIDENTSUBJECTSsub.

Please help.
