Although your code passes task 1 you will want to revise it before proceeding to task 2. From the task 1 instructions:

The while loop should continue as long as the value of counter is less than the number of items in the array. (Hint: You can get that number by using the count property)

Your current code uses 1 instead of the array count so will not include all items in the array for task 2.

In task 2 you will use counter as an index to reference values in the numbers array. Each time through the loop assign an array value to the variable newValue. Then use that to calculate the sum. The task 2 instructions provide you with the code for the sum. You just need to figure out how to assign an array value to newValue.
