You must be using a mail client that is rendering HTML, or nabble.
In yours you had the ampersand character. He actually had the ampersand character then amp;.
I'm not sure what my client does with escaping, so I'll try three things.
You need to replace the ampersands with & & "Ampersand Character"+"amp;"I'm not sure which of the above will appear right, but I hope I got the idea across.
