Here's the html/code for the form. I hope this is what you wanted. Like I said, I'm really new at this, I just started reading up on it this morning.
Thanks for looking at it, if this is the wrong info please let me know.
Edited to add: the error says "forbidden" if that makes any difference.

you may still come to class without your puppy. As soon as your puppy receives
