Can you clarify your question a little more. Are you looking for a running total, the total for the row, or the column total. You did say supplier total, are you wanting to count number of supplier or the amount? If I can picture your example correctly, I see four columns but cannot picture what right or left supplier column are you talking about? Do you simply want to insert a new column? Please provide specifics, and I am sure lot of us here can provide assistance.

Thank you !!
