Why are my style sheets all listed on one line?

I'm still fairly new to PHP, so there may be a simple fix for my relatively trivial complaint. I'm using an included page as a head section. It works fine, except that when preview a page and view the source, all the style sheets are displayed on one looooong line, like this: </script><link href="../../css/ref.css" rel="stylesheet" type="text/css"><link href="../../css/na/a1.css" rel="stylesheet" type="text/css" /><link href=".css" rel="stylesheet" type="text/css" /><link href="../../css/nations.css" rel="alternate stylesheet" type="text/css" title="Nations" /> It looks like they won't scroll across THIS page, so here's a more clear example: <stylesheet1><stylesheet2><stylesheet3><stylesheet4> What I want is a normal style sheet display, like this: <stylesheet1> <stylesheet2> <stylesheet3> <stylesheet4> Do you know what causes this and if there's a fix? I posted some code from the head section and main page below. Thanks! * * * * * * * * * * HEAD SECTION (included page; ../../includes/ref/head.php) <?php $todayDate = date("m-d-Y"); echo '<title>Freedomware &gt; ' . $myname .
