Dear Tammy,
Thanks again for your reply.
As for question 2, the URL you provided gave me some other options, though it would best if the unit/currency is still outputted together with the number figure, but not in another column.
As for question 1, I have got the following screen shot about InfoObject for you. I am just puzzled about that the currency/unit can be outputted in the row header on the left when row shares the same currency/unit, while the currency/unit cannot be outputted in the column header above when column shares the same currency/unit. They don't follow the same rule.... (1-1), (2-1),(2-3)
