I have a field entitled "Lung_lunc". It contains some "0" values and the rest are values > 0. I want to turn those "0" values, into "0.0001". I have added a new field: "Lung_lunca", and I want to use a IF statement in Field calculator, to do so. I have tried the version in the image, but when I run the script, nothing changes (the values remain the same, as in the previous field). I have looked over similar questions here, but did not manage to find a solution.
How should I modify the script, in order to work?
P.S. I have made sure that both "Lung_lunc" and "Lung_lunca" are double fields, so they accept decimals.
