having problems with Challenge task 3 of 3 where I am trying to introduce a try block

Any suggestions

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

You forgot to indent the last line of code a little more.

Also, I don't think you need an else in this situation.

You don't need a "count" variable, you can just return the value of the two numbers right away. (You don't need to do this, but this reduces code a little :smile:)

This should be your complete code after doing both of these:

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

Good luck! ~Alex
