Really stumped on where this Syntax Error is...


"Syntax Error: Unexpected token"


var cashRegister = {
    total:0,
    lastTransactionAmount = 0;
    add: function(itemCost) {
        this.total +=  itemCost;
        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() {
        tototal = total - lastTransactionAmount;
        return tototal;
        }
    
};

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.voidLastTransaction();
cashRegister.scan('eggs',3);

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


#2

Does it provide a line where this "unexpected token" is?


#3

No it doesn't :confused:


#4

var cashRegister = {
    total:0,
    lastTransactionAmount: 0
    add: function(itemCost) {
        this.total +=  itemCost;
        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() {
        tototal = total - lastTransactionAmount;
        return tototal;
        }
    
};

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.voidLastTransaction();
cashRegister.scan('eggs',3);

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

So found out the problem but now the error says "Oops, try again. false."

Remember to put "this" before "lastTransactionAmount"

add: function(itemCost) {
        this.total +=  itemCost;
        this.lastTransactionAmount = itemCost;
    },

also you wrote "tototal", and you never defined a variable called "tototal"; it must be "total" and its valule needs to be: total = total - lastTransactionAmount (remember how to write this?) ..once you make the operation you don't need to return the value.
