If you want people to help troubleshoot, you should post code with proper formatting.

See the guide here Markdown for Codewars.

```python

k = 1

c = []

```

becomes:

def order(sentence):
  k = 1
  c = []
  etc.

Looking at your solution quickly, it seems that you aren't returning anything you are just using print(c) - try with return(c) instead to see if that works.
