Ed,
I selected the option to create and address list in publisher. There's no
field for "Barcode" in the publisher data base so I added it. After
following the instructions from the link you posted, I still can't get a
barcode to appear. I'm assuming that once you insert the zip code field and
barcode fields onto the envelope a barcode will appear.
When using my Corel, all I have to do is put in a zip code then click on
"barcode" and the correct barcode appears.
