When I export the text file from openproject() it works fine and exported the text file but when I export from other fn such as openuser() its show NameError: free variable 'mywidget' referenced before assignment in enclosing scope. How come it does work on one function but not on others? If I separate each defined function into separate projects, its working fine but when I merge three functions into one GUI, the first one is only working. I'm sorry for my stupid codes as I'm new to Python and also to this forum. Thank you.
Below is my code>

It is because you used command=save1() in the following line:
button4 = Button(user, text="Export", command=save1())
which execute save1() immediately and at that time mywidget is not defined yet.
You should use command=save1 instead:
button4 = Button(user, text="Export", command=save1)
