Different logo for page

ok so I have attempted adding the following code to functions.php but I keep getting a syntax error on all posts and pages…

<?php

add_filter('tc_logo_src', 'my_logo');
function my_logo($original){
    if ( is_page("tax-accountability") )
        return esc_url('http://www.taxpayersunitedofamerica.org/wp-content/uploads/TAX-ACCOUNTABILITY-LOGO-2home.png');
    else
        return $original;
}
