Open Pop Up Form Using Anothers Forms Name As The Criteria

okay, i have presented my database to my boss.

apart from the ongoing problem of trying to get a listbox and subform the same to the user, he has asked me to do something more

he wants me to be able to select from the menu, a selction that will open up a pop up form, from which notes can be made relating to the originating form

i presume the linking criteria will use the form name plus the record criteria the originating form is bound to

any help on how i go about this will be greatly appreciated
