What is the benefit of using a string as the key as opposed to just typing the intended name in?

I'm writing a web-based game that involves clicking links on various sites on the internet. I know it sounds strange but the basic premise is that you start on my page where you click a link to some page on another site.

Hi friends, ok, I'm back. I totally simplified my problem to just three simple fields and I'm still stuck on the same line using the addJSONData method.
