@DavidH.Bennett Any reason why the difference?

I just tried Josh's code, didn't work. Tried Rajesh's class and it did.

You seem to have reused the code from the answer by @JoshM. However, you have modified and extended the code. What was the reason to do so? What does your code better/differently than that of @JoshM? Such kind of explanation would help readers to understand your solution.

hey if you want me to sent you the content returned by link in the object i surely will.
