Hey, I made this code: for(var i = 0; i < offer.itemsToReceive.length; i++){getPrices(offer.itemsToReceive).then(function(val){console.log(val);}).catch(function(err) {console.log(err);});} it prints the values of the items i receive in the trade.How do i make it so it just prints the total value, so all the item prices in one total.
