Hmm this is actually correct, but not very clear I agree. In chapter 4, the parameters list only contained a dict with the name="text" key-value. In chapter 5, we replace that dict with one that has the name=email key-value. We could have left the other dict and it would not have been a problem, that's what I meant. Am I clear? Can you think of a better way to express it?
name="text"
name=email
