I have set the code for the cancel button but nothing happens when it is clicked. Any suggestions why?  I thought this was the code to set it:

settings(3) = New settingType
        settings(3).settingName = settingNameEnum.hostedPaymentReturnOptions.ToString
        settings(3).settingValue = "{""url"": ""http://mysite/training-center/training-locations"", ""urlText"": ""Continue"", ""cancelUrl"": ""http://mysite/training-center/training-schedule"", ""cancelUrlText"": ""Cancel""}"
        

It works for the "Continue" button which appears on the receipt page but the "Cancel" button that is shown on the payment page ("Pay" and "Cancel" buttons are shown) does nothing.

Thanks.
