Hi! What is wrong with my code? Here it is, thanks!

var cashRegister = {
    total:0,
    //Dont forget to add your property
    lastTransactionAmount: 0,
    add: function(itemCost) {
        this.total +=  itemCost;
        this.lastTransactionAmount = 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
    voidLastTransaction: function() {
        total -= this.lastTransactionAmount;
    }
    
};

#2

"this.lastTransactionAmount = itemCost" need semi-colon at the end.


#3

Now the error message says "SyntaxError: Unexpected token ("


#4

change it to
voidLastTransaction: function() {
this.total -= this.lastTransactionAmount;
}
