Customize e-commerce shopping cart view.

I wanted to implement another view of shipping cart.
Usually, it can be done, by theme’ing wpsc-cart_widget.php in your theme directory.

But for some reasons, this didn’t work for me.

I specified Shopping cart type as Widget in Settings -> Store -> Presentation.
added the following code to my theme template:

and the following code to functions.php:

 
function wpsc_shopping_cart1( $input = null, $override_state = null ) {
        global $wpdb;
                        $cart = $_SESSION['nzshpcrt_cart'];
                        echo "
";
                        echo wpsc_shopping_basket_internals1( $cart );
                        echo "
";

        return $input;
}

function wpsc_shopping_basket_internals1( $cart, $quantity_limit = false, $no_title=false ) {
        global $wpdb;
        $display_state = '';

        if ( ( ( ( isset( $_SESSION['slider_state'] ) && $_SESSION['slider_state'] == 0) ) || ( wpsc_cart_item_count() < 1 ) ) && ( get_option( 'show_sliding_cart' ) == 1 ) )
                $display_state = "style='display: none;'";

        echo "
";

        include_once('wpsc-cart_widget.php' );

        echo "
";
}

Then customize wpsc-cart_widget.php file in your them directory
