Reclass Field Calculator problem

MartaPo

Hi,

I am having a massive problem with running this script in ArcGIS 10.3 Field Calculator Python

def Reclass(CLASS):
if CLASS=="2":
return "2a"
elif CLASS=="3"
return "3a"
else:
return (CLASS)

Any help much appreciated.

Thank you,

Marta

If Xander's suggestion doesn't work, it would be helpful if you explain what exactly isn't working, including posting the error message(s).

Hi Xander,

It is working now. I have not realised that the spacing is so important. Thank you
