Forcing specific styles on specific pages

[Borisch]

Hey,

I'm currently developing my new site and I would like to debug it both as a guest and user/admin. So far I've been using index.php?styleid=2 to set a specific style. However, this doesn't work for guests and so I would like to force a style on the pages I'm debugging.

I've tried doing something like this:

$styleid = 2;
eval('print_output("' . fetch_template('TEMPLATE') . '");');

But it's not actually doing anything, I'm still only getting a white page unless I log in and choose a specific style. Any ideas?
