Styles again.

Yesterday I installed a styles hack.
What should happen is when you hit the site, you should see a logo up top which is predominantly black, and the rest of the page is white with a right column.
If you look in that column, there is a ‘Styles’ menu, and you can click the colours to set them differently. When you return, the colours you last saw the site in will be remembered and used again.
There was a fault in that I had forgotten to set the default, but although I have set that, there may still be a problem due to the fact that I altered the hacks structure to suit me and make directories less cluttered. So it may not work if I got a / or a . in the wrong place.
Let me know please ?
