Error - 'None Type' has no attribute 'config'

Question

Error Code

Whenever I run this , it either shows 'None Type' has no attribute 'config' or 'None Type' has no attribute 'get'. How to solve this?

def trip1():
   global trip
   trip=trip*2
   print(trip)

def trip2():
   global trip
   trip=trip*3
   print(trip)

root.mainloop() 

I tried multiple options , making a nested function , a new button to pull it off so I could display a spinbox number inside a toplevel window which is triggered using another button.
