加载多个外部css问题

I found an example here https://code.google.com/p/fastcssloader/ for loading several stylesheets using only 1 link rel=...

Everything worked fine until I tried to use the code linked above.

My link code:

<link rel="stylesheet" type="text/css" href="/styles/css_include.php" />

I literally copied the code and put the above .php in the directory where my styleshees are but no matter which style I choose from the options page I created (which stores a cookie telling which stylesheet to load on all pages) it always loads the second one in that directory. Any idea what is happening?

EDIT: This was using Chrome. Apparently the second stylesheet is cached somewhere (even though I must have pressed ctrl f5 a dozen times) because when I open the page in IE8 (dont ask) the stylesheet is not loaded at all. What am I doing wrong? Why doesn't the code load the stylesheets even though I copied it exactly? Is it the directory? I tried making the directory "." and "/styles" and a combination of them all.

EDIT: I moved the css_include.php file into the directory where my pages are stored and referenced it accordingly and now it doesn't load any stylesheet at all, so at least keeping css_include.php in the /styles directory loaded SOMETHING. I am at a loss here...
