Hi~~

def Reclass(arg1, arg2):
    if arg1 in ["222", "333"]:
        return None
    else:
        return arg2

#code

Reclass(!NAME!, !PNAME!)

Please see why there is an error.

#1 You have !PNAME! as one of the parameters and you are trying to calculate the PNAME field.. You can't use the PNAME field to calculate itself

#2 Assuming that you have to calculate values into the PNAME field and you need values from 2 fields, you didn't pass in two arguments to the script in the Pname section the expression line

# 3 AND you need to remove the

#code

Reclass(!Name!, !Pname!)

in the Code block section. Those lines are not supposed to be included in the code block.

I think you just copied and pasted an example and put some of the wrong things in the wrong place

I haven't figured out where the right place is yet.
I'll do a little more research.

It's a little difficult.

Thank you for your reply.
