Aha! We noticed the uppercase "S" and it worked! THANKS SO MUCH!!!!
One more question. Upon the button press, the lights stop twinkling but still remain on. Would there happen to be an easy change to a variable to make them turn off altogether instead of stopping twinkling?
Honestly, I think he's happy the way it is, but if there's a variable we can change in the code to have the button turn the lights off, we'd love to give it a try?
Thanks!
