thanks so much for your time on this post first.
1. I just wonder that it is possible to store current order value of customer with their E-mail.
2. When I store the order value can I store "Current order value" and "Total Order Value"?
Total Order value = total value of all order from the customer (Include current order)
Order A $ 10 in Jan 2017
Order B $ 20 in Feb 2017
current order value $ 30
"Current Order value" = $30
"Total Order Value" = $ 60
10 + 20 +30 = 60
I hope this question makes sense.
