Don't feel bad about this. This is something that messes a lot of people
up. The browser knows where your headers end and where content begins by
adding blank line between the headers and the rest of the page. ALL headers
must come before any content is printed to the page. PHP will give you that
error if you attempt to write a new header. So in fact your problem is not
on Line 13.. but is actually on Line 11. There are at least two ways to
avoid this...
1. Don't print content before headers. :)
2. Use output buffering to write the whole page before it is outputed to the
browser.
Hope this helps,
