I see absolutely nothing wrong with this one folks! Please help me. Thanks :)

I tested this in Visual Studio with my own list as the argument input and it worked... Not sure what's wrong :( Maybe I'm misunderstanding the question! thanks in advance!

instances.py 
def combiner(argument):
    a = ""
    b = 0
    c = ""
    d = 0
    for i in argument:
        if isinstance(i,str):        
            a += "".join(i)
    for i in argument:
        if isinstance(i,int):
            b += i
    for i in argument:
        if isinstance(i,float):
            d += i
    b += d
    c += a
    c += str(b)
    return c
