Ms Lemon. The main secret to Blickies which work is to make sure don't accidentally put in anything which doesn't belong. Your link was as follows :-
http://www.mudcat.org/www.myspace.com/shotdogs
Snuffy's link was this :-
http://www.myspace.com/shotdogs
Yours doesn't work because the browser is trying to search INSIDE Mudcat for the Myspace address.
Hope that helps.
Quack!
Geoff.
