I'm looking at this example from W3Schools:
The problem I see here is that the server-side function is invoked whether or not the client-side function returned true. It's not really doing a real Cancel. How do I modify this so that the server-side function is only invoked IF the client-side function returns true. If the client-side function returns false, then the server-side function should not be invoked.
Thanks so much for your assistance.
