I was on the phone Friday for an hour plus with enterprise support. No one had an answer how to even change the vendor number. 

As far as the error there is nothing to do with that item. That is the item info we use when we add an item to an order. I have no idea why it turns red. Ultimately I may need to do something a little different with the vendor numbers anyway. But i want to see if this works first. 

If you know someone at intuit that might actually be able to help with this let me know and I can contact them.
