'PRE' Syntax on "When modified record saved" Workflows

 Good day.

I'm having an issue with "When Modified Record Saved" workflows. I was trying to Send an Email if a status was changedo n a particular Order record.

However, the syntax won't seem to work. I would like to ask for an advise on the following syntax if I got it incorrectly.

[<plWorking_ITAG>]=LookupValue("OCC_CUST_ZOBJ_3_LOV_6", "Middle East & Africa") AND (PRE('<plOrder_Status_ITAG>')<>[<plOrder_Status_ITAG>] AND [<plOrder_Status_ITAG>]=LookupValue("OCC_CUST_ZOBJ_3_LOV_1", "Complete")) AND [<plOwning_Organization_ITAG>]=LookupValue("OCC_CUST_ZOBJ_3_LOV_23", "Rosemount Analytical") AND (JoinFieldValue('<Opportunity>',[<OpportunityId>],'<OwnerId>') <> UserValue('<UserId>') OR JoinFieldValue('<Opportunity>',[<OpportunityId>],'<OwnerId>') = UserValue('<UserId>')) AND (JoinFieldValue('<Opportunity>',[<OpportunityId>],'<CreatedByEmailAddress>') <> UserValue('<EMailAddr>') OR JoinFieldValue('<Opportunity>',[<OpportunityId>],'<CreatedByEmailAddress>') = UserValue('<EMailAddr>'))
