In order for this to work, you'll also need to create a data layer variable called "items" on any page you want to set the product IDs and product categories. You can set all of them here:

<script>
  dataLayer = [{ 
    items : [
      {
        product_id: '1414',
        product_category: 'Shoes'
      },
      {
        product_id: 'ABC',
        product_category: 'Toys'
      }
     ]
    }];
</script>
