The decs match, so check to make sure you had the right number of sts when you divided for the V or had them divided right. There should have been 32 sts on each side.
BO 4, k26, k2tog and you're at the V. Then do the other side, k2tog and k30 to the end. BO 4 sts on the WS and work across both shoulder sts. Then you dec at the beg of the row, both sides of the neck and at the end of the row.
