Of course I did. I know what's maybe wrong!

Try step 2 again.
I colored the url by mistake and it won't be parsed in the [php] bb code.
Guess you copied the color bb code, too^^! I have to appologize that mistake



Before (wrong):
In headertemplate search:

PHP Code:

<script type="text/javascript" src="[COLOR="Red"]http://www.yourdomain.com/flash_fireworks.js[/COLOR]"></script> 


After (i hope right now ):
replace:

PHP Code:

<script type="text/javascript" src="http://www.yourdomain.com/flash_fireworks.js"></script>    

Hope it finally works for you now :)
