Partly, I was curious to see how you made the modifications. But my problem is that it's stuck on 'Loading...'.

Mine would get stuck on loading if I had an error afterwards. Try commenting everything and uncomment lines slowly? I used alert('') to check if it reached certain parts (also to output values to see if they were correct)

Or is it getting stuck anyway with my code like that? x.x I think regex made the page slower the first time I used it, so it would take a while to calculate the result
