Trying to correlate functions in Tkinter

  for-loop, function, loops, python, tkinter

I have this GUI in Tkinter where you can press a a button and after that a toplevel appears where you can input data in different entries. That data is saved in an Excel file. I am stuck right now when im trying to exit from place n° 1 (after pressing button 1 and top.withdraw from that toplevel) and going to place n° 2 (by pressing button 2). What i want is that the for loop i made for the entries re-start in place n° 2. Instead, what is actually doing is continuing the for loop in the same stop it was in place n° 1. Is continuing the for loop, and i want to break it somehow to start over again in place n° 2. Since this code has 500+ lines i will paste here the proper part of the code and specifically the part i thing must me modified is the last part of the code. Thank you all !
