When a name is not contained in quotation marks, the characters after the first character of the name must be uppercase A - Z, pound sign (#), at sign (@), dollar sign ($), 0 - 9, underscore (_), or period.
Response: Either change the name to contain only valid characters, or specify quotation marks around the name and make sure the characters inside the quotation are valid.
