Additional data at checkout form... how do you pull that data to use in code?

I have added a form to collect additional data at checkout for a pricing plan. How do I retrieve the data from this form to use in my code? I also want to use this data to update custom contact fields but I think if someone can answer my first question I can figure that out.

To do this, go to WooCommerce » Settings and click on the ‘Advanced’ tab. After that, open the ‘Checkout page’ dropdown and start typing in the URL of the custom checkout page you just created. https://www.ariseportal.org/

I am trying to find the data stored in the Additional Info section for Pricing Plans. I see what you mention for eCommerce but the data I am looking for is under Pricing Plans. I think I may have to redesign how I am doing this. Thank you.

I am having the same problem here. It’s quite frustrating to see the information on the wix dashboard and have no way of accessing it in wix CMS. This needs sorting!
