I am doing a challenge for Google FooBar, and am having trouble submitting my code.  My code is correct, and I have checked my program output against the answers provided by Google, and my output is correct.  However, when I try and submit, I get a Error 403: Permission denied message.  I cannot submit feedback either because I receive the same error message.  Does any one have any advice?
you have to sign in and associate your foobar to your Gmail then you should be able to request a new challenge.
