Notice Use of undefined constant jQuery assumed 'jQuery' Error

Line 55 Notice: Use of undefined constant

THis is in index.php of silk ajax comments folder.

Code was:

function google_jquery() {
	if ( ! jQuery ) {
		wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"), false);
		wp_enqueue_script('jquery');
	}
}

Changed to

function google_jquery() {
	if ( ! 'jQuery' ) {
		wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"), false);
		wp_enqueue_script('jquery');
	}
}

Notice the single quotes around the jQuery…

if ( ! 'jQuery' )

There was also a comment here…

It uses wp_script_is( ‘jquery’ ) but I didn’t research how.

Thanks,
