What should be incredibly simple has taken me hours, and still no closer. I have two numeric summary fields in a crystal report, and i need a third field to show the difference (subtract) between them.
Have tried to figure out the formula, but when I use the field names with a "@" in front of them I get "Field is not known".
As these are summary fields in a footer section i cannot (for other reasons also) use the table values for this.
I know this must be simple - please help,
