Change Position on the Product Page

Hi there,
thanks for the fantastic plugin its very useful!
I’m trying to change the position of the shipping date on the Product Page and I currently have the following code, which throws me an error so its not working.

function move_estimated_shipping() {
remove_action( ‘woocommerce_after_add_to_cart_form’, array( WCESD_Public(), ‘wc_esd_show_date’ ) );
add_action( ‘woocommerce_after_add_to_cart_button’, array( WCESD_Public(), ‘wc_esd_show_date’ ) );
}

add_action( ‘init’, ‘move_estimated_shipping’, 10 );

Can you let me know how to adept it to get it working?
Many thanks in advynce ??
