    A few things. You don't have the complete code listed or the error you are seeing. This information could help us help you.

    I would also do some searches as these issues have been touched on before here. And I would try your js in a static html page to make sure it works in a clean environment.

    If you change those print "<html here>"; to print qq(<html here>); (or q() see perlop), I bet it will work. Other then that we'll need a better description of the problems your having with it.

      Thanks that certainly helped me out

    There is nothing in your 'print' lines that needs to be interpolated, you could just change for example:
    print "<html><head><script="javascript" src="demo.js"</script><title>T +ESTING</title></head>";
    print '<html><head><script="javascript" src="demo.js"</script><title>T +ESTING</title></head>';
    Not sure if this is your issue, but you have unescaped "s in the line.

    Can I suggest that you put the closing angle bracket on the script tag? ie. change:
    <script="javascript" src="demo.js"</script>
    <script="javascript" src="demo.js"></script>

    Personally I would change that entire line to read:

    <script type=\"text/javascript\" src=\"demo.js\"></script>
    Why, you ask? Well a tag name (such as script) should have a space before the first argument (type=\"text/javascript\"). Also the quote marks should be escaped within a Perl string as mentioned above.

    update: reformatted mis-escaped <code> tag.

    update: accidently pressed the update button twice.

      Nice catch, I completely missed that one. Especially after the cutting, and pasting. ;)
