AttributeError: tuple obj has no attribute in .py script with PySimpleGUI

Question

I've written a Python script that cycles through a folder structure and looks inside the files for a given value. The script works well, but now I'm trying to add a GUI and can't get passed this error. The error occurs when clicking 'search' in the gui, triggering the event.

File "C:\Users\xxxxx\Documents\Python Scripts\FileContentsSearcherwWithFileWrite_GUIv02.py", line 66, in event, values = window().read AttributeError: 'tuple' object has no attribute 'read'

I think I understand that there is a tuple somewhere in the script that the window is trying to read/display, but I can't figure out what it could be. Is anyone able to help?

Thanks
