Couple things: i don't think you need the single quotes around the USERID or REDUCTION values.
Also, do you have a field in your data model called 'REDUCTION' ? And does that field contain values like 'domain\username' ? Bascially the field header should be the name of the field, and the value should be one or more values
Something like the following, where 'REGION' is a field in the data model and 'USA' and 'EUROPE' are actual values in that field.
