What is wrong with my code?

Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError. Inside the except block, return None. If you're following the structure from the videos, add an else: for your final return of the added floats.

trial.py 
def add (arg1,arg2):
    return(float(arg1) + float(arg2))
try:
    return float(arg1) + float(agr2)
    except ValueError:
        return None
    else:
        return float(arg1) + (arg2)

Sisley;

Look at how things are progressing through your above code and remember that once a return statement is reached a function typically will not do any further commands. As such, how would anything enter into the try: block? Also, double check your indentation.

Post back if you are still stuck.
