To change the data type of a field, I've added a new field and I want to use the field calculator to copy the values in the original field. But for some feature classes I cannot select the field calculator. Does anyone know why this might be happening? [ATTACH=CONFIG]26487[/ATTACH]
I found a way around the problem but you can't add a field if you are in edit mode. For some feature classes I could use the Field Calculator and for others I couldn't, which was unusual. I just added all of the fields first and then went into edit mode and used the field calculator.
