Well, without further clarification on what you're facing, I'd guess that at some point you've got a form open that will allow you to capture both the old port ID and the new port ID in text fields. At that point you can create a new query with critera like "(PortID = Forms!ThatForm!txtOldPort) OR (PortID = Forms!ThatForm!txtNewPort)" and print them in a 2-column subreport/subform, or you can have two side-by-side subreports/subforms which are driven by the boxes separately. There's almost certainly a better way... Rich or Pat or one of the other AccessGods may know (they may have even mailed you off-list already, since you mentioned it was urgent). I hope you got it working.
