Sillycase Challenge

Can anyone tell me why my code is not working for this challenge? It works when I run it from the console on my computer. So I'm kind of at a loss as to why it's not working here.

I get an error message saying that slice indices must be integers or None or have an index method.

silly.py 
# The first half of the string, rounded with round(), should be lowercased.
# The second half should be uppercased.
# E.g. "Treehouse" should come back as "treeHOUSE"
def sillycase(text):
    middleIndex = int(round(len(text))) / 2
    firstHalf = text[:middleIndex].lower()
    secondHalf = text[middleIndex:].upper()
    combined = firstHalf + secondHalf
    return combined

Well. middleIndex = int(round(len(text))) / 2 there's a problem in this line when you're calculating the middleindex. It should be

middleIndex = int(round(len(text)/2))

Thanks. That did the trick. Any idea why it worked when I ran it from the console on my computer? I tried printing the value of middleIndex to check for the number it was outputting and it was the same regardless of where I divided by 2. Is the reader in Treehouse just looking for a specific syntax in this case?

try test with len(text) in odd number, and you'll see the difference.
