Error connecting my work to the re-framework

I have a problem when connecting my workflow to the orchestrator, a simple summary of my project is that it is a folder reader and then registers in an excel, my goal is to make it portable, for this at the beginning of my work there is a " assign “called” address "where the folder to be read is specified, then if I want to make it portable that folder destination can change, it depends on which pc is installed.
My goal is to make a cell called “Address” in the re-framework excel file, and then place the destination of the folder for this purpose, the robot would no longer have to be entered and only the route from the excel “Config”, but I have not succeeded in making it connect to my work.
through arguments I try to locate it but I have errors like l-invalid and so
they know some way to solve this problem
Thank you very much in advance
