Typo in sample

Chapter 9: Lambda expressions and expression trees: P245, section 9.3.5

The sample code on page 245 is incorrect. It should be this:

T runningTotal = initialValue;
foreach (T item in values)
{
   runningTotal = Operator.Add(runningTotal, item);
}

Note the second argument, which should be item, not values.
