missing “product ID”

hi,

thanks for the plugin and your support.

Adwords gives following errors. Where should i look?

“93% of your AdWords tag activity is missing “product ID”
To tailor your dynamic ads to visitors’ activity on your website, make sure this parameter is included in your tag.”

“There are problems with some of your custom parameters for Retail (AdWords)”

The tag is active but we found some issues with your custom parameters.
Check that all your custom parameters are implemented correctly. Custom parameters are necessary to enable dynamic remarketing.

(i use product bundles plugin. and i have product bundles.)

Only 0 of 17 page visits that have passed an ID (or 0%) match approved IDs in your Merchant Center feed
Dynamic ads can only show items in the Merchant Center feed that have been approved.
Items can be disapproved for several reasons including deleted products, unavailable images, or the sensitive nature of the products.

Some values for the custom parameter “ecomm_pagetype” are missing
The tag is not passing all required values for “ecomm_pagetype”.
Consider adding the remarketing tag with custom parameter “ecomm_pagetype” to all your webpages.
