Summation from a python list

I can't see my error, I'm trying to add the integers passed in from the list.

Alternatively I tried using the sum() function but could not pass the test:

def add_list(numlist):
    total = sum(numlist)
    return total

[MOD: added ```python formatting -cf]

You posted code does pass Task 1. Alternately you could loop over the input list:

def add_list(lst):
    count = 0
    for item in lst:
        count = count + item
    return count

Hey Chris Freeman , thanks for the help. I did not initialize the count to 0. Passed the test now.
