First, this should be adequate:

       Set fld = tdf.CreateField("fldTest", dbGUID)

Next, I don't think you can do this other than manually in design
view, indeed not if you wish to have two autonumber columns.

This may be one of the situations where you need to create an empty
table with the required structure and copy it to the backend.

If you find out a method to add the field in code, please share.
