Keeps saying task one is no longer passing. What am i doing wrong?

I just can’t figure it out and I don’t quite understand Try and except

trial.py 
def add(a,b):
    try:
        count = int(input())
    except ValueError:
        return(None)
    else:
        return(float(a)+float(b))

The message "Task 1 is no longer passing" is usually caused by an syntax error. In this case, it is caused by a change in functionality. The input statement will not work for functions defined in challenges since there is no "user" present to provide input. The challenge checker will call the defined function with specific arguments and compare the returned value to the expected value.

Hint: replace the input statement with two statements that attempt to convert the inputs "a" and "b" into float values (such as a = float(a)) then change the return statement to return the sum of these two converted values.
