Let's make sure we're always working with floats. Convert your arguments to floats....

Not sure what I'm doing wrong here...

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

def add(x, y):

try:                                                                                                            
   a = float(x)
   b = float(y)
except ValueError:
  return None
else:
  return a + b

a = add(2,4) print (a)

here is what I have, make sure you indent. I did not have any problems.

You need to indent everything after the def add(x,y):

Otherwise you have an empty function and some random code floating in your workflow.

def add(x, y):
  try:
    a = float(x)
    b = float(y)
  except ValueError:
    return None
  else:
    return a + b
