Hi all. Hope everyone had a great new year! I am trying to create a chart expression by including the sum of another expression. Code for new expression: sum([Rep Sales]) + [Year Sales] where [Rep Sales] is another expression on the chart, and [Year Sales] is a table field. The expression editor is throwing the following error: Bad field name(s): [Rep Sales]. Can anyone advise? 1/13/2010 2:27:49 AM
