Cant paste HTML code into footer on template

[CoffeeGuy]

I have installed a new online customer support chat. I have it all setup, except this HTML code that has to be added. See image.... 

The online chat module says I have to add it to the footer, which it clearly shows here that it is, and I added the HTML code in the "Optional HTML code" section of the template.

Can anyone tell me why I am getting the error in screen shot #2?

Thanks!

I'd start with some trivial HTML to see whether the module rejects HTML in general or if there's something wrong with the code you paste. Trivial HTML would be <div></div>.
