I want to add vertical scrollbar to a frame frm3 (in the below code), the scrollbar is appearing but it is not spanning the entire frm3. I have followed the steps in the solution
Vertical scrollbar for frame in Tkinter, Python
I want the scrollbar covering the entire frm3, and the canvas/frame spanning the entire frm3. Not sure why it is showing in the weird way.
The source code
