That code looks like it should work. Make sure that you don't have any previous versions of the code above that one. During testing, you may try changing the kick message somehow so you can be sure that the right code is activating. For example, make the kick message appear in blue instead of black, or add a reference number/letter/word to the end of the kick message. Once the code is working exactly how you want, you can remove the extra bits from the message.
