A blog reader by the name of Kevin of http://www.thebrosource.com/ alerted me to the <textarea< tag in place of the more complicated codes for scroll box. I tested it at Testing Blogger: testarea tag in place of scroll box.
The code is as follows:
<textarea cols="50" rows="30">type your text here</textarea>
where cols="50" defines the box for the text area to be 50 characters wide and rows="30" defines the number of rows to be 30. Note that the test shows that you should type the text without using the ENTER key otherwise the line break will be represented by the line break tag <br />
