Why Treehouse has not accepted my solution ?

Dear all this cose below is working my computer, does anybody have an idea what is the problem with it ?

wordcount.py
# E.g. word_count("I do not like it Sam I Am") gets back a dictionary like:
# {'i': 2, 'do': 1, 'it': 1, 'sam': 1, 'like': 1, 'not': 1, 'am': 1}
# Lowercase the string to make it easier.
def word_count(wordtocount):
    splitted = wordtocount.lower().split()
    splitted_uniq = set(splitted)
    result = {}

    for word in splitted_uniq:
        counter = wordtocount.count(word)
        result[word] = counter

    return(result)
