Both of you have HTML in your target file. You will notice, I hope, that my file does not have any formatting code as it is never meant to be viewed in anyone's browser, there is no link to it from any page, etc. It MUST have a blank line below it in order to read properly as I have laid out the script. It MUST NOT have any HTML tags in it. If you have a <!DOCTYPE declaration or an <HTML> tag, then you have formatted the file as .html.

<blank line>
<end of file>
Notice the complete lack of formatting.
