Hi Mark,

c smith is certainly right to suggest that you ought to specify a bit
more about what the symptoms are that you would like help diagnosing.

That said, what should be the result if an item with a sticker price
of 1.35 is purchased? Perhaps thinking about that and comparing the
following will help:

IDLE 2.6.6
>>> user_input = "1.35"
>>> purchaseAmount = int(user_input)

Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
purchaseAmount = int(user_input)
ValueError: invalid literal for int() with base 10: '1.35'
>>> user_input = float("1.35")
>>> purchaseAmount = int(user_input)
>>> purchaseAmount
1
>>>

Best,
