Help! Viewing order items on User Profile

I have a big dilemma here. I am building an e-commerce platform for my employer. It is a hardware procurement app. So in my profile I have floating group that get information of the order I want to track. The thing is I am trying to display the items related to that order. I have been trying for the passed few days to debug. But it seems like there’s is something I am really missing.

This is how I set up everything. I got a Cart Item & Order Item Data Type. Crat item is used for the user’s cart. Order Item serves as a backup cart which should allow me to access the products the user added to their cart. So that after the checkout, when the user’s cart is cleared I am able to display the order items the user have selected and link them to their related order.

Here the current workflows I have and how I set things up. Thanks in advance for your help.
