What is wrong with this function?

I made a function which I think is right according to the question though it says there is an error so... someone help please

functions.py 
# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.

def add_list(array):
  total = 0
  for number in array:
    total = total + number
    return total

Your return needs to be tabbed in once so it's not a part of the for loop. Currently you will exit the function with the return after the first iteration.
