Hi all,I'm using the Field Calculator with some basic Python syntax to recalculate a field. The new data is coming from a joined Excel worksheet. My expression is:!'Commercial-Active$'.OLD![:-3]
When I run this I get the error: "A field name was not found or there were unbalanced quotation marks." I know the field name is correct because I'm selecting it as-is from the Fields box. Does anyone know what this is all about?Thanks!
