Hi there! It's that float can only accept one item at a time. But you were on the right track! So you need to try to convert each one individually and then add them together:

def add(num1,num2):
    return float(num1) + float(num2)

Hope this helps :sparkles:

As I understand you're also experiencing trouble with the last part, I'll show you how I did that one.

def add(num1,num2):
    try:
        return float(num1) + float(num2)
    except ValueError:
        return None

Good luck! :thumbsup:
