DECLARE
   Seq1 PLS_INTEGER := 0;
BEGIN
   SELECT   COUNT (1) INTO   Seq1
     FROM   ALL_OBJECTS
    WHERE   OBJECT_NAMEe = UPPER ('tblTrackerSeq')
            AND OBJECT_TYPE = 'SEQUENCE';

    IF Seq1 = 0 THEN

    DECLARE TracNewSeq varchar2(100 char);
BEGIN
SELECT 'CREATE SEQUENCE tblTrackerSeq MINVALUE 0 START WITH '||(MAX(tblTrackerSeq_ID)+1)||' INCREMENT BY 1 CACHE 100'   INTO TracNewSeq FROM tblTracker;
EXECUTE IMMEDIATE TracNewSeq;
END;
    END IF;
END;

Answer : encountered symbol ""

Little correction PL/SQL can have multiple DECLARE statments but it should be grouped logically.

Here is example

8:
9:
10:
