I spent a lot of time because I didn't understand that in this case, when: numSeconds = 3; the task only need to display "3 2 1 Go!". I have try many times to understand how to print no. 4 when numSeconds = 3; impossible task 😪 if numSeconds = 4(but is not!) then print(anotherString) but in this task is not the case. Keep code!

Good advice. Do not look at the examples as given in the previous lesson. They will just confuse you. Find a source outside of CodeGym if you want to understand how this works as the information given in lesson 8 and 9 are not working. Try for yourself!

The only problem is i am able to display the exact output but not able to do it together this means at numSeconds=3; the output for numSeconds=3 is correct but wrong for numSeconds=4 and vice versa
