Not quite sure if this is what you're driving at. Assume a multi-select list box (which you want the bound column from) on a form and a command button which opens a report in preview mode. Here's one way:
Private Sub cmdPreview_Click()
Dim lst As ListBox
Dim vItem As Variant, sCriteria As String
sCriteria = ""
Set lst = Me.lstItems
For Each vItem In lst.ItemsSelected
sCriteria = sCriteria & "," & lst.ItemData(vItem)
Next vItem
DoCmd.OpenReport "reportname", acViewPreview, "ID IN (" & Mid(sCriteria, 2) & ")"
End Sub
