I am trying to Migrate a rollup from the free edition for RollupHelper to Declarative Lookup Rollup Summaries. The purpose of the rollup is to total the totalprice of specific products associated with the opportunity. But I keep encountering the following error. 

Error:
Relationship Criteria: Relationship Criteria 'CONTAINS( Product2.ProductCode ,"Unify") OR CONTAINS( Product2.ProductCode ,"Ext Camera") OR CONTAINS( Product2.ProductCode ,"WT") OR CONTAINS( Product2.ProductCode ,"CellCam") OR CONTAINS( Product2.ProductCode ,"WXP") OR CONTAINS( Product2.ProductCode ,"W450") OR CONTAINS( Product2.ProductCode ,"W461") OR CONTAINS( Product2.ProductCode ,"W460") OR CONTAINS( Product2.ProductCode ,"W410") OR CONTAINS( Product2.ProductCode ,"WXL") OR CONTAINS( Product2.ProductCode ,"Camera") AND opportunity.iswon = TRUE AND NOT(CONTAINS( Opportunity.Name,"CG Internal Marketing/R&D EVO Devices") AND NOT(CONTAINS( Opportunity.Name,"Conga") AND NOT(CONTAINS( Opportunity.Name,"Demo") AND NOT(CONTAINS( Opportunity.Name,"Return") AND NOT(CONTAINS( Opportunity.Name,"Credit") AND ISPICKVAL(Opportunity.Type = "New Business") AND opportunity.closedate >= 2020-01-01' is not valid, see SOQL documentation http://www.salesforce.com/us/developer/docs/soql_sosl/Content/sforce_api_calls_soql_select_conditionexpression.htm, error is 'unexpected token: ',''

The formula I am using is as follows:
CONTAINS( Product2.ProductCode ,"Unify") OR CONTAINS( Product2.ProductCode ,"Ext Camera") OR CONTAINS( Product2.ProductCode ,"WT") OR CONTAINS( Product2.ProductCode ,"CellCam") OR CONTAINS( Product2.ProductCode ,"WXP") OR CONTAINS( Product2.ProductCode ,"W450") OR CONTAINS( Product2.ProductCode ,"W461") OR CONTAINS( Product2.ProductCode ,"W460") OR CONTAINS( Product2.ProductCode ,"W410") OR CONTAINS( Product2.ProductCode ,"WXL") OR CONTAINS( Product2.ProductCode ,"Camera") AND opportunity.iswon = TRUE AND NOT(CONTAINS( Opportunity.Name,"CG Internal Marketing/R&D EVO Devices") AND NOT(CONTAINS( Opportunity.Name,"Conga") AND NOT(CONTAINS( Opportunity.Name,"Demo") AND NOT(CONTAINS( Opportunity.Name,"Return") AND NOT(CONTAINS( Opportunity.Name,"Credit") AND ISPICKVAL(Opportunity.Type = "New Business") AND opportunity.closedate >= 2020-01-01))))
