Am having a major head explosion with this one.

Current line

Code:
<link href="<?php echo($globalvar['default_style']) ?>.css/main.css" rel="stylesheet" type="text/css">
the href should be showing something like "./themes/standard/css/main.css" which it appears to do when I interrogate the php variable, however the css is not being applied ... not sure what I am missing and quite possibly need a debug tool of some kind.

Can you have dynamic links to style sheets in the head section of an html page?
