Pulling data from a workbook with a different sheet name

[pragmatic123]

I have VBA code that pulls and combines data from two excel files in a specified folder path, and these excel files have the same sheet name. I am trying to pull data from another excel file but the sheet name is different. I will post my code so it is visible. How can I modify this code?
