What am I doing wrong? (I hope I didn't get you confused, but I don't know how to do latex.)

If I am reading it right, you have 4 planes of charge such that a Gaussian cylinder cutting all 4 planes encloses zero charge. By Gauss' law the integral of the normal component of the field over the surface will be zero. Since the field from any single plane of charge has reflection symmetry, and is independent of the distance from the plane, the fields outside the plates will be zero. Between the plates you will have contributions from all four planes, with a downward contribution from the s1 surfaces and upward from the s2 surfaces.
