Split Error occurs when you choose Split in Advanced Print Options in some versions. It says, Error when executing the method PrintOptions2 at line number 276.
This error is fixed in Big Business 13.51.
Split sends a form like Invoice Plain Paper to two Destinations by creating two rows for the form. Choose Split in settings and then set one to Printer and one to Email. Split can be preset in the Printing Defaults found in Preferences like Customer Prefs.
