Read my message again. If the message already includes text and other formatting, you have to build a string that includes *the original text and formatting* plus *your new text* and then set HTMLBody to that string.
The original text is contained in the original HTMLBody property of the message you create with the template. You will have to work with the HTML tags with string functions or, if you're more comfortable with straight HTML, use GetInspector.HTMLEditor to return an HTML Document Object model representation of the HTML content.
Please take the time to quote the original message so that people reading your current response can understand what you're talking about. Otherwise, you may not receive the answer you're looking for.
