i try to use the next code to load cforms II plugin only on my CONTACT PAGE

(http://www.deliciousdays.com/cforms-plugin/)

#/template/functions.php

    add_action( 'wp_print_scripts', ' ', 100 );
    function my_deregister_javascript() {
    if ( !is_page('Contact') ) {
    wp_deregister_script( 'cforms' );
    }
    }

    add_action( 'wp_print_styles', 'my_deregister_styles', 100 );
    function my_deregister_styles() {
    if ( !is_page('contact') ) {
    wp_deregister_style( 'cforms' );
    wp_deregister_style( 'style' ); 
    }
    }

but doesn't work

the code worked for contact form 7 ( http://wordpress.org/extend/plugins/contact-form-7/)
