If I only have one product item in Apple Pay, how would I detect a total? My app is a donation platform, so I don't need to actually ship anything, but would like contact info. I have a number of errors that I have tried to figure out to debug to no avail. Any help is appreciated.Also I keep getting this error (this was the same as the sample code given from WWDC).This is in my BuyTicketViewController.swift file. if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(BuyTicketViewController.paymentNetworks) { let button = PKPaymentButton(type: .Buy, style,: .Black) button.addTarget(self, action: applePayButtonPressed, forControlEvents: .TouchUpInside) button.center = applePayView.center button.autoresizingMask = [.FlexibleLeftMargin, .FlexibleRightMarin] applePayView.addSubview(button) } }The error says 'expected declaration.'The sample says to use else (for traditional checkout). When I put that it, it breaks the rest of my code and I get lots of errors.line 8 - eror on MerchantIDline 9 - error
