Good Afternoon, I would really appreciate some help. Can someone help me? I read others request of help and It should be good.

Thanks

this is my code and it should just work instead I get the error below. I am sure it's a silly mistake.

```
def square(n):
"""Returns the square of a number."""
squared = n**2
print "%d squared is %d." % (n, squared)
return squared
# Call the square function on line 9! Make sure to
# include the number 10 between the parentheses.
square(10)
error = Oops, try again. Did you remember to call square(10) on line 9?
```
