A field reference in your formula included more than one field name, such as 'Sales Revenue' when both Sales and Revenue are separate fields, or you tried to include a field name in a calculated item formula.Calculated item formulas cannot include field names, and can include names of items only from the field in which you are inserting the calculated item.
