wherever I add the try block, I get the error that Task 1 is no longer working

the prompt specifies that a try block should be added above where I return the added floats. But I cannot find a place to add the try block that does not ruin the code that it's expecting to read.

trial.py 
    def add(num1,num2):
        try:
            num1 = float()
            num2 = float()
        except ValueError:
            return None
    else:
        return (float(num1)+float(num2))
    add(2,3)

Hey Julia!

Well a couple of things here. First of all, you do not say:

num1 = float() # This is in fact saying that num1 == 0.0

Instead go ahead and say:

num1 = float(num1)

Secondly you do not need to say return (float(num1)+float(num2)) seeing as we have already converted them. Instead just add them as they already are. Finally im not sure what you're trying to do with your final statement:

add(2,3) # This dosent make any sense

At the end you should have something looking like this:

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

Hope this helps!

Thank you so much. That all makes sense and it worked when I followed your instructions.
