I am adding a text/string field, "countyname", to a shapefile table. When I use Field Calculator to change the new fields to "Delaware", I get this error message
The calculated value is invalid for the row with ObjectID = 0. For example, the calculated value may be too large for the field or you may be trying to add a string to a number field. This row will not be updated. Do you want to process the rest of the rows?
It goes on with a warning about what happens if I say yes or no. I select Yes and the process fails. I don't know why this is happening or why it's referring to ObjectID = 0, when there is no such ObjectID. ObjectID starts with 1.
Solved! Go to Solution.
Sometimes field calculator is buggy. Are you in an edit session? Have you tried restarting ArcMap and making sure this file isn't open anywhere else? Sometimes it takes a few times and some troubleshooting to make the field calculator work.
