On this challenge, my solution seems to be working properly however, when I press Check Answer it tells me to " Double the value at position `index`

in `lst`

"

Here’s my solution:

```
new_list = []
def double_index(lst, index):
if index >= len(lst):
return lst
else:
for item in lst:
if lst.index(item) == index:
doubled_item = item * 2
new_list.append(doubled_item)
else:
new_list.append(item)
return new_list
print(double_index([3, 8, -10, 12], 2))
```

Solution provided:

```
def double_index(lst, index):
# Checks to see if index is too big
if index >= len(lst):
return lst
else:
# Gets the original list up to index
new_lst = lst[0:index]
# Adds double the value at index to the new list
new_lst.append(lst[index]*2)
# Adds the rest of the original list
new_lst = new_lst + lst[index+1:]
return new_lst
```

Is this just an error because I’m not doing it the way they have shown? Or is my code not doing what they’re actually asking it to do
