    Hi! Because this code has no reference to the order in question, it cannot determine where to retrieve the data. Just like the example for the product function from the documentation you’re linking to, you should be able to pass the order ID with the function.

    Based on this example:

    
<?php wccf_print_product_prop_value(array('key' => 'UNIQUE_FIELD_KEY', 'item_id' => 'PRODUCT_ID')); ?>

    I’m guessing that the syntax for the wccf_print_checkout_field_value that you’re using should be like this:

    
<?php wccf_print_checkout_field_value(array('key' => 'purchase_order_number', 'item_id' => $order->get_id())); ?>

    If that doesn’t work, I recommend contacting RightPress about this since it’s not directly covered in the documentation. They should be able to help with this.

    Good luck!
