[Plugin: NextGEN Gallery] Display problem from SELECT COUNT NGGPICTURES

This code inserted into a page worked with older versions of NextGen Gallery and has not worked since version 1.9.6
<? php global $ wpdb; echo intval ($ wpdb-> get_var (“SELECT COUNT (*) FROM $ wpdb-> nggpictures”));?>
The result is a partial display code
Someone has an idea?
thank you
