Hi not able to understand what the error is

Here is my code

def checkio(number: int) -> str:
    if (number%5 == 0 and number%3 == 0):
        return ("Fizz Buzz")
    elif (number%3 == 0):
        return ("Fizz")
    elif (number%5 == 0):
        return ("BUZZ")
    else:
        return (str(number))
