From a table shoppingbasket I need the total delivery costs
In the table I have these columns Suplier, deliv-costs.
This looks logic to me ( "sum(max(deliv-costs)) group by suplier" ) but that does not work and I know why, so i do not need an explenation about this.
My question is what will work
PS Please do not mind my english
