Syntax Error on line 1

Hiya, just wondering if anyone can help. Im trying to put a different logo on a different index page in my site. I have tried the code but i think its not working becuase of the Syntax Error on line 1? 

"Your code" is a link, not code.

What do you want to do? Can you share link to your site?
