I'm not sure what your code looks like, but I do know that textareas are EXTREMELY different from a standard text box.
Example of correctly "pre-valued" text box and text area:
Text Box:
<input type="text" value="predefined text">
You might notice that I have used the "value" attribute to populate this text box.
Textarea:
<textarea name="myTextArea">predefined text</textarea>
This time instead of using the "value" attribute, I actually used the textarea as I would an anchor (hyperlink) tag. Much different!!
Both of these examples will come out on the page with the phrase "predefined text" in them.
Hope that helps...
