Sidebar on pages … blix theme.. help plz

Hi,

Recently setup my site http://www.craigrigby.co.uk with a modified blix theme…

I’d like to show the sidebar on all the pages.. (if you click on cars or rover 220 gsi the sidebar disappears)

Can anyone tell me how to alter this so the sidebar is there throughout? I think it would improve navigation and consistancy through the site…

Cheers
