Multiplication, challenge task 1 of 2: __mul__ and __rmul__

I'm not sure what I'm doing wrong here. I just get a generic "Bummer: Try again!"

Any tips would be appreciated.

numstring.py 
class NumString:
    def __init__(self, value):
        self.value = str(value)

    def __str__(self):
         return self.value

    def __int__(self):
        return int(self.value)

    def __float__(self):
        return float(self.value)

    def __add__(self, other):
        if '.' in self.value:
            return float(self) + other
        return int(self) + other

    def __radd__(self, other):
        return self + other

    def __iadd__(self, other):
        self.value = self + other
        return self.value

    def __mul__(self, other):
        if '.' in self.value:
            return float(self) * other
        return int(self) * other

    def __rmul__(self, other):
        return other * self

I wouldn't think it would matter but all I did is reverse the order to:

 def __rmul__(self, other):
        return self * other

and it passed

Thank you. I think my brain must've turned to mush on this one!
