Accessing Global Variables defined in ThisWorkbook Module

To the ExcelForum Community,

What I've tried to do is define a global variable upon Excel opening this worksheet. Hence, why the declaration must appear in the ThisWorkbook Module.

The problem is that when I try to access the same variable from a different module, it appears that the information previously stored in the global variable is lost.

I've attached a simplified version of the worksheet. For this to work, I would like Cell E1 and F1 to show the same result when the "Setup" button is clicked.

Appreciate any help!
