As you can see, I am getting  >>...<< as output, but I really want  >>...<< instead. Can you please help?

Ideally, the example code and data should be brief and runnable. Please see the Short, Self Contained, Correct (Compilable), Example discussion. Please also see How do I post a question effectively? and How (Not) To Ask A Question. Please help us to help you.
