Problem with TwotyFruity.cs in Chapter 2

I ran this example and it did not print out what was expected.
I used the one that was on the CD. i.e. I didn't introduce errors by typing it in myself.
Here is the output I got.

Total pieces of fruit: 1
Total Price of Fruit: $1.15

This doesn't seem to be what the book says it should.

I printed out the value of $numFruitTypes and it doesn't seem to be initialized correctly with the following line:

$numFruitTypes = InitializeFruit();

Don't know if that is the problem or something in the function call is causing the problem.

Does anyone know what the problem is?

Thanks.
