Hello!
Thank you for your fast reply. I copy the modified code to Custom PHP code to modify output, but nothing has changed.
I have sku and quantity fields.
The problem is if an order contains only 1 item, this item quantity write to the first product column (for example D2 cell). I want to reach that for example at D2 cell contains only product 1 quantities, E2 contains only product 2 quantities, and F2 contains only product 3 quantities.
Best regards!
