Parse error – Can't open my site

Hi,

I have this suffusion 3.6.6 site http://top10bestchristmasgiftideas2010.com which I added
add_action( ‘wp_print_scripts’, ‘disable_autosave’ );
function disable_autosave() {
wp_deregister_script(‘autosave’);
}

into the ‘functions.php’ file in the theme directory with the intention to disable the autosave function but the outcome is I can’t open my website now, there is this message saying:

Parse error: syntax error, unexpected $end in /home/content/79/6656279/html/wp-content/themes/suffusion/functions.php

I went into the hosting control center trying to look for ‘functions.php’ file in the theme directory but can’t find it.

May I know what should I do now?

Thanks.
