TypeError: unsupported operand type(s) for -: 'tuple' and 'tuple'

[Peter Bismuti]

Can anyone explain this error message?

Traceback (most recent call last):
  File "/acct/pjb9508/RAT/Scripts/PyQt/RatDialog.py", line 30, in
NewClipButton_clicked
    self.rat.planeClip(self.o,"SQUARE"+str(self.squareCounter),width,origin)
  File "/acct/pjb9508/RAT/Scripts/PyQt/rat.py", line 12, in planeClip
    plane1[1] = origin[1]-width
TypeError: unsupported operand type(s) for -: 'tuple' and 'tuple'
