Neil,

You have posted the same question three times in less than 50 minutes probably without even noticing that the previous questions have been answered.

If you do not understand the answer, or if you need more information, you should post a follow-up question instead of posting the same question again. Another teacher might answer the question over again and that slows the answering process.

Thanks for your understanding.
