[Tutor] What's the problem with my SpinSpeeds.py?

[Dick Moores]

Why am I unable to use countUsingRange(n) instead of countUsingRange(25000)?

When I do so, I get

Traceback (most recent call last):
   File "C:/Python23/1.py", line 17, in -toplevel-
     rangeTime = t.timeit(repetitions)
   File "C:\Python23\lib\timeit.py", line 158, in timeit
     return self.inner(it, self.timer)
   File "<timeit-src>", line 6, in inner
NameError: global name 'n' is not defined

Is this fixable?
