Going on just that sample, there's no issue. As it works the first time,
there isn't a problem with it not getting included. Have you tried it on
other browsers to see what happens there? Also, Firefox has a brilliant
addon called Firebug, which can show you the contents of included .js
files on your page, which will show up any problems you may have.
Aside from these points, have you a good reason for including a PHP file
that just outputs javascript? Why not just include the .js file as part
of the header?
Also, your script tags need a type attribute:
<script language="javascript" type="text/javascript">
And lastly, instead of lots and lots of echo statements in your page,
have you looked at heredoc and nowdoc syntax in PHP?
echo <<<EOC
lots and lots of output lines go here.
EOC;
