How to create report for "best customers of all time" ?

Hello,
I wonder if is it possible to create a custom report for "best customers of all time" with both their name/email listed and the total amount they spent on the shop for the given period.
I tried to play with the reports tool but I've only been able to get a list of the customers name/email.

Thank you

Hi,

The reports on the customers do display the total amount too on my end:

So I'm not sure what you did.

Thanks for the snapshot, I sorted it out.
