Variables for Pinterest in GTM

[MAD King]

Hello,

I hope I am posting this into the right forum.
I am trying to integrate Pinterest into GTM, but having troubles with the variables.

The Pinterest Tag Helper shows me this:

Add to cart event was sent successfully with warnings.
No enhanced match was found
Value is missing
Type:
Javascript
Page URL:
https://www.xxxxx.com/
Event Data
Value: (missing)

and this:

Checkout event was sent successfully with warnings.
No enhanced match was found
Order ID is missing
Value is missing
Type:
Javascript
Page URL:
https://www.xxxxx.com/
Event Data
Order ID: (missing)
Value: (missing)

Anyone who can help me?

Thanks
