You've got the loop correct; the last part of the loop code needs to be the increment of counter, as you have done - just put that on a separate line without the square brackets.
Now, the first line inside the loop needs to add an element of numbers into the accumulative variable named sum.
How to access numbers? Use counter inside square brackets, like numbers[counter]. Use += to add numbers[counter] into sum then increment counter as above.
Does that make sense?
Steve.
