How to display message based on cart total in Woocommerce

Question

I am trying to display a message in a custom page template based on the cart total using a function but it not displaying my message.

Please see function below:

add_shortcode( 'custom_order, 'woocommerce_order_subtotal' );
function woocommerce_order_subtotal(){ 

    $sub = WC()->cart->total();

    // if for the subtotal:

    if ($sub > 100)) {
        echo "Hello world!";
    }
}

You should get the subtotal when calling the cart not the total

   add_shortcode( 'custom_order, 'woocommerce_order_subtotal' );
    function woocommerce_order_subtotal(){ 

        $sub = WC()->cart->total(); //this is wrong here you gettin total not subtotal
         $sub = WC()->cart->subtotal
         //Or this following         
         $sub = WC()->cart->get_cart_subtotal()

        // if for the subtotal:

        if ($sub > 100)) {
            echo "Hello world!";
    }
   }
