Ecommerce tracking doesn't send any data

Thank you! it was a last version from this forum (How to set up ecommerce tracking?)… I change the code:

_paq.push([
“ecommerceOrder”,
[
{
sku: “2128”,
name: “Renoir, Auguste - Váza chryzantém (Dahlias)”,
category: “101”,
price: 714,
quantity: 1
},],
{ orderId: “2306195640”,
grandTotal: “714”}]);

and I got any parser error but this: “Uncaught ReferenceError: _paq is not defined”. I guess that I need to initialize all the _paq function somewhere… But I don’t know how :slight_smile:
