opencart script fixing -- 3

Job ID: 37004346

Budget: $10 – $30 USD

Query wholesale stock by model in the cart.
We switched from the journal theme to a new theme and the query and css do not work.
I would like to find an opencart specialist for repairs.
I have a script (wsdl) that can query the wholesale stock in real time. It currently runs on opencart version 2.0.3.1 and would need to be converted to run on 3.0.3.8 luxshop theme.
Functionality:
I put x products in the cart and when I open the cart it automatically runs the script and returns the response in xml and updates the stock of products in the opencart database. The returned values will be displayed in the cart as shown in the attached images. The task is to make the script work on the new theme (not just the css)
