# need help to pass this

def add(x, y): # number 1 and 2 return x + y # number 3 def add(x, y): f_x, f_y = float(x), float(y) return f_x + f_y def add(num1, num2): try: a = float(num1) # <-- indent b = float(num2) # <-- indent except ValueError: return None else: return(a + b)

I have been on this for 2 weeks need the code to move on for challenge 3

trial.py
```def add(x, y):    # number 1 and 2
return x + y   # number 3
f_x, f_y = float(x), float(y)
return f_x + f_y
def add(num1, num2): try: a = float(num1) # <-- indent b = float(num2) # <-- indent except ValueError: return None else: return(a + b)
```

Well first off your add function is defined three times. It should only be defined once. At the end of step 2 my code looks like this:

```def add (x,y):
return float(x) + float(y)
```

At the end of step 3 my code looks like this:

```def add (x,y):
try:
return float(x) + float(y)
except ValueError:
return None
```

The only real difference between the two is to make sure the conversion to floats was successful.

Try again. This code (which passed step 3) worked for me. Make sure nothing else is in there except these lines.

```def add(x,y):
try:
return float(x) + float(y)
except ValueError:
return None
```

this code does not work for challege 3

it still will not work
