You've got some real problems with indices; when you start an index subscript at a value not equal to ORIGIN, mathcad fills in the unspecified positions. I've tried to sort this out (without really understanding what you're doing), but your solve block needs three vectors and one of them has far fewer members than the other two. At any rate, this should point you in the right direction.
