Creating a Trigger on Oracle

This is being done on Oracle 11, and I'm trying to create a trigger where if the incoming meets certain values, to update another table.

--CREATE TRIGGER ON ITX
CREATE OR REPLACE TRIGGER TRG_I_LAST_RECEIVED
  AFTER INSERT ON ITEM_TRANSACTION_LOG
    FOR EACH ROW
      WHEN (
        NEW.ITEM_CONDITION_ID =  5005                                               -- REPAIRED
        AND NEW.WORKCENTER_ID IN (5001,5006,5063,5000,5022,5062)   -- EWRC
        AND NEW.ORDER_ITEM_OPER_ID = 5009                                      -- Perform Exit Routing
      )
BEGIN
  UPDATE PART 
  SET LAST_REPAIRED = SYSDATE
  WHERE PART_NO = :NEW.ITEM_PART_NO
END;

When I do, it adds it, but I get this (ORA-24344):

Now, I understand SQL fairly well (T-SQL) and maybe I'm missing something - can someone eyeball this and tell me why it's not valid?

EDIT: The issue was missing semi-colon at the end of the update statement. Oracle's semi-colon discrepencies drive me bonkers sometimes.

Here's the correct statement, and thanks to Justin Cave for finding it:

--CREATE TRIGGER ON ITX
CREATE OR REPLACE TRIGGER TRG_I_LAST_RECEIVED
  AFTER INSERT ON ITEM_TRANSACTION_LOG
    FOR EACH ROW
      WHEN (
        NEW.ITEM_CONDITION_ID =  5005                                               -- REPAIRED
        AND NEW.WORKCENTER_ID IN (5001,5006,5063,5000,5022,5062)   -- EWRC
        AND NEW.ORDER_ITEM_OPER_ID = 5009                                      -- Perform Exit Routing
      )
BEGIN
  UPDATE PART 
  SET LAST_REPAIRED = SYSDATE
  WHERE PART_NO = :NEW.ITEM_PART_NO;    --add that semicolon!
END;
