Error Declaring FK and PK on same Line

[jo15765]

I am creating a table with this code:

CREATE TABLE ENROLLMENT
  (
  Sid Number(5) CONSTRAINTS ENROLLMENT_Sid_pk Primary KEY AND ENROLLMENT_Sid_fk REFERENCES STUDENT,
  Csecid NUMBER(8) CONSTRAINTS ENROLLMENT_csecid_pk Primary Key AND ENROLLMENT_csecid_fk REFERENCES COURSE_SELECTION,
  Grade CHAR(1) CHECK(Grade IN (A, B, C, D, F, I, W))
  );

But I get this error:
Error @ line 3
00907: missing right parenthesis

When I import the script file it cuts off Line 3 to read as:
Sid NUMBER(5) CONSTRAINTS ENROLLMENT_Sid_pk PRIMARY KEY AND ENROLLMENT_Sid_fk References Stud
