I am having an issue integrating Avantlink Order Tracking and Order confirmation code with Paid membership pro WP. I was sent documents from avantlinks and paid membership pro to follow and implement the task but it did not work with me.

    Here are the codes which needs to be integrate with Paid membership pro. 
    Remember I am using Divi theme on my wp site.

    <script type="text/javascript">
    var _AvantMetrics = _AvantMetrics || [];
    _AvantMetrics.push(['order',{ order_id:'[ORDER_ID]',
    amount:'[ORDER_AMOUNT]',     
    state:'[BILLING_STATE]', country:'[BILLING_COUNTRY]' }]);
    _AvantMetrics.push(['item',{ order_id:'[ORDER_ID]', 
    parent_sku:'[ITEM_PARENT_SKU]', variant_sku:'[ITEM_VARIANT_SKU]', 
    price:'[ITEM_PRICE]', qty:'[ITEM_QUANTITY]' }]);
    </script>

    The code above is for order confirmation and that Avantlink order 
    confirmation code requires different array of variables to verify. And here 
    are the paid membership pro variables that need to be set with the code 
    above i am not sure how to do that

    $order->membership_id
    $pmpro_invoice->billing->state
    $pmpro_invoice->billing->country
    $pmpro_invoice->total
    $pmpro_invoice->discount_code->code
    $pmpro_invoice->accountnumber

Can someone help me how to use these variables in the avantlink code so it works fine

Thank you for your help
