CRM 2016: Error CS0103: The name 'item' does not exist in the current context

I am working on C# development for a CRM 2016 on premise project.  The solution includes classes, plugins, workflows and unit test projects.  

The problem I am having is with code taken from the Order class (which is working) that submits information to a mainframe for paint colors.  

I want to replicate the Order code in the Change Order class.  Most of the Order code copies over to the Change Order class without error,  but I am getting the "Error CS0103: The name 'item' does not exist in the current context" message for 6 lines of code.

I  have tried adding a Using statement, adding a reference, reviewing Stack Overflow suggestions but so far no success in clearing the errors.

I have included the Order class code (working version) and the Change Order code (with errors) below.  I have added comments (//ERROR ON LINE BELOW)  to the 6 lines of Change Order code where I getting the error on the 'item' reference

This is urgent and I am open to online sessions if that is required.

Thank you
