I continue to be unable to assign products to cars. Using ? I get the proper menu for products already available with the a boxcar. I use the + sign to see what additional products might be available but the Products window appears and is empty. I have either deleted or disabled all products & commodities that have any error condirion. Finally, just enabled orange juice and still no products appear in the list window. I have done an extended/extensive repair. Looking at the script error it just seems to say a null field was found. But without a listing there is little help there.:'(
