  We show that the standard generating functions for genus 0 two-point twisted
Gromov-Witten invariants arising from concavex vector bundles over symplectic
toric manifolds are explicit transforms of the corresponding one-point
generating functions. The latter are, in turn, transforms of Givental's
J-function. We obtain closed formulas for them and, in particular, for
two-point Gromov-Witten invariants of non-negative toric complete
intersections. Such two-point formulas should play a key role in the
computation of genus 1 Gromov-Witten invariants (closed, open, and unoriented)
of toric complete intersections as they indeed do in the case of the projective
complete intersections.
