even after saving the number of days, it's just shows up as NaN days and Nan Hours
please login option to have the list saved
Great idea but not working for me - often doesn't add problems, and when it does the countdown is either 'time to re-do' or NaN, regardless of the timer number. Any ideas how to fix this?
