On the first page, after save and submit (the code is the default on page 1 : how it works) I type in an integer and the response is very slow and then it tells me what I've chosen (as it should) and then nothing whatsoever happens. The save and submit button remains blue but the text disappears but the next section/page is never called. I've reloaded the page and the same thing happens ?? Any help or is there an issue with the Ruby section this evening ? It does seem to be being a bit laggy.
I just quit Firefox and then restarted it and logged back into coadecademy and the browser is behaving okay and the page loaded fine after giving an integer. So this just seems to have been a Firefox issue.
