Homero,
I took a look at page 3 of the 2006 Annual Report. There's no error, but it can be a bit confusing. The graph shows sales in billions of dollars. On first glance, the data in the table seems to be incompatible because it says "Sales to customers (in millions)." But if you look at the numbers, it gives 2006 sales as $53,324 million, which is the same as $53.3 billion. If you wrote the entire number out, with all of the zeroes, it would be the same. It's just two different ways of writing the same thing.
