Query Set-up with NOT

[TitaniaTiO2]

Ok I am not sure how to set-up this query / code

My tables are:

tblPerson
PersonID
LastName
FirstName

tblDocument
DocumentNumber
DocumentTitle

tblTraining
TrainingID
PersonID
DocumentNumber
....

I want a form where I can select a DocumentNumber from cmbDocumentNumber
(list of all distinct DocumentNumbers from tblDocument (Know how to set this
part up)

I then want to display a listbox that shows only the employees NOT trained
to that DocumentNumber


Maybe I am just having a brain fart.

The problem is that when I set up my attempts at the query, it only shows
the employees that are NOT trained to Document X but are trained to some
other document. I want it to show employees even if they are not trained to
any documents

Thanks for the help!
Does this even make senese?

Select tblDocument.DocumentNumber, tblPerson.PersonID
FROM tblDocument, tblPerson
WHERE DocumentNumber=Forms!MyForm!cboDocumentNumber

gives you a deliberate cartesian product. Then you can subtract.
