Treehouse TeacherHi there! Because I feel like you have mostly the right idea, I'm going to give some hints here as I think it will be a better overall learning experience for you.
- You do not need to set up a new variable such as you've done with
newValue - Nothing needs to be printed. You may remove the print statement.
- We use counter to hold our place through the loop
- Access the element of the
numbersarray using the index of counter such asnumbers[counter] - Add the number in the array to the current running total of
sum - increment
counterafter adding the number to sum... not before
I hope this helps, but let me know if you're still stuck!
