Hi,
I have what I think would be a very easy request for someone who knows what they are doing.

In the admin->reports->customer order totals it displays the total amount spent (excluding shipping) by each customer in my default currency which is great.

Can any tell me if it is possible to have an extra line on this report or an extra report that adds all these totals together to show me the total amount for all customers. That would then give me a better idea of total profit.

If this is possible could anyone tell me how to do it, I assume it's just a case of sum all values and display but I don't have much of a clue about php.

Thanks
