I have an App I want to build, but I do not know how to use this product, HTML, JS well enough to build the app. I have the layout done, just not the backend. Anyone able to help?

Please answer this with more details please. I am having the same problem and this answer does not help me. What are working area components? When do you add them? If you have a template without one (like shown above), is it too late to add one?
