I would be happy to help you with coding for the sign up button. I went to your website and could not see the button on your website to see what could be happening. Can you let me know where the button is on your website or send me a screenshot of how it looks when you add the button?
I see you chatted with an agent about using the embedded form. When you place your embedded code in your website you may have to make some changes so the website can display the code correctly. This great Constant Contact blog post walks you through how to make some of those changes.
