When I run the script, I am getting:

"Oops, try again. median([1]) returned 0 instead of 1"

If I comment out the return after the IF and replace it with "Return 1" (troubleshooting step only), then the script moves on to finding the median of [4,5,5,4], and I get the error:

"Oops, try again. median([4, 5, 5, 4]) resulted in an error: 2 is not in list"

I have reviewed the logic deveral times, but cant seem to see where I'm going wrong.

Help?

```
def median(orig_list):
sort_list = sorted(orig_list) #put the list in order
x = len(sort_list) #the list is x terms long
if x == 1:
return sort_list.index(1) # if list has only 1 item, just return it
elif x % 2 == 0: # its even, find the middle two terms and average them.
return (sort_list.index(x/2) + sort_list.index(x/2 +1))/2.0
else: #it is odd, find the middle term and return it
return sort_list.index(x/2 + 0.5)
```
