Did you check the more detailed errors in the browser console (f12) ?

3

from the browser console you can see userful error messages like

AssertionError: 'Perc[226 chars]F  E \n     u  o  n \n     s  o  t \n     i  d[134 chars]   t'
             != 'Perc[226 chars]F  E  \n     u  o  n  \n     s  o  t  \n     i[148 chars] t  '

the top is your code, the bottom is the expected output
it looks like there is a mismatch with the spaces
