When this error occurs in the Influence Diagram it is usually because an expression contains a semicolon. A semicolon is never needed in the Model Window.
In DPL code, this error means that DPL was expecting to find a reserved word such as "value", "chance", "decision", or "const" and found something else instead. This can happen when a reserved word is typed incorrectly or when a line ends with two semicolons. Remember that all reserved words must be typed in lower case.
