Answer 1

If I look at the bold statements in your markup, I can see that you've written id ="btcusd" when it probably should be id="btcusd" (without space before your equals sign).

I don't know if this is what causes your issues or not. It's hard to know what errors you are getting since in your example it seems to be plain syntax errors when trying to run your code snippet.
