Error On Question 4/7

echo $tens{2};
using the square brackets is not working in this exercise, most likely a typo in the correction engine

I tried "echo $tens{2};" and "echo $tens[2];", but neither works. In both cases, the window on the right shows what I believe is the correct answer (30). Shouldn't one of those work? The "save and submit code" button basically only works once, sometimes not even that, before I have to refresh the page. This module is incredibly frustrating.

I'm having the same problem, have to reload the page a nearly all the time, not sure what's wrong, but it is really frusterating.
