To add a wee bit of big-picture to the comments here ... if you looked (say, with the Firebug debugger, or most browsers in “Developer” mode) at the HTML-source of any page at all which contains a <frame>, you would see the tag ... but nothing of what the tag refers to. This is because it’s not there: frames are separately-fetched. They are very much like “pages within pages,” because the browser initiates a separate HTML turn-around to get them, and more-or-less manages them in isolation from the “host” page. And, basically, that’s what your script has to do, too: it must find the frame-references, determine what they call for, and then fetch what they call for. (As the FAQ somewhat tersely explains.)
