How do I get the square up payment info on the thank you page?

Setting up a thank you page with the payment info but can't seem to find the field values to Squareup?

They are accessible in the notification & auto responder email, why not for the thank you page?

You can do that by adding the My Products Form Fields in the Thank You page. 

Please give it a try and if you have questions, please let us know. Thank you.
