It sounds like the pattern is missing. You can copy the pattern on a piece of paper and then draw the dividing lines and number each piece. Leave the pattern whole because you need it to sew your fabric pieces onto. When you cut out your pieces, cut them larger so you can have the 1/4" seam.
You could also contact the magazine and see if they can send you the pattern you are missing. If you have the name of the block you can check pp sites and get the pattern. there are a lot of free pattern sites out there.
