I honestly Have no Idea what I am doing Wrong.

I have been on this for 30 mins, I am probably missing something small if you can help that would be great.

trial.py 
def add(first, second): 
try:
    except ValueError:
    return None
else:
    first=float(first)
    second=float(second)
    return (first+second)

Python understands what code goes in what block by how much you indent it. Right now, Python sees the start of a function, then a ton of unrelated code. All your code after your function definition needs to be indented a level to tell Python that it goes inside that function. Also, your ordering of everything is a little out of whack. You need to place things that could fail in the try block, and what to do if it fails in the except block. An else isn't necessary here
