Parse error

I was trying to tweak the functions.php file of my wp theme and ended up with a “Parse error: syntax error, unexpected ‘<‘….”. I looked up the code line and could see no extra <. I tried replacing the code with code from the functions.php file on my computer but no luck. Now I can’t do anything on my site. I only get this error message if I try to log out, click on any other php files, or click on anything in the menu. Anyone know how to fix this?
