#1


I cannot find the error, I tried and edited it 5 times now but idk where is it, can you help me please


oops, try again. false (it gives 8.55)


var cashRegister = {
    total:0,
    //Dont forget to add your property
    add: function(itemCost) {
        this.total +=  itemCost;
        this.lastTrans = itemCost;
    },
    scan: function(item,quantity) {
        switch (item) {
        case "eggs": this.add(0.98 * quantity); break;
        case "milk": this.add(1.23 * quantity); break;
        case "magazine": this.add(4.99 * quantity); break;
        case "chocolate": this.add(0.45 * quantity); break;
        }
        return true;
    },
    //Add the voidLastTransaction Method here
    voidLastTrans: function (){
        this.total -= this.lastTrans;
    }    
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);

//Void the last transaction and then add 3 instead
cashRegister.voidLastTrans();
cashRegister.scan('chocolate', 3);

//Show the total bill
console.log('Your bill is '+cashRegister.total);

Did you mean to write,

this.lastTransactionAmount

as instructed? Remember to declare the property,

total: 0,
lastTransactionAmount: 0,

LIkewise,

voidLastTransaction:

just changed the names of every lastTrans to lastTransaction and it worked... still worked as lastTrans but it didn't accepted the result as true, thanks :slight_smile:
