Hello
Am trying to calculate the percentage area of the land cover classes in my map and keep on getting this error message (see attached). I tried changing the setting when adding the new field (percentage) so that I can click on the allow null, but it is greyed out. I tried clicking on the error message and it tells me there is no solution at this time.
Please can anyone help?
Thanks.
This worked, thanks.
comma could be localization
Thanks, removed comma and it worked.
The percentage field had zeros (0) after I added the field (see attached), made sure data type was double. I can't edit the column for null when adding field. It opens greyed out.
Could you delete the comma in the denominator (15675.2), and try again?
Do you have any records with null values in that field?
I would add a new field (eg double, Area2, make sure it isn't nullable)
Then try the expression again.
