In this paper, the second order m-point boundary value problem u''(t) + a(t)u'(t) + f{t,u) = 0, 0 les t les 1, u'(0) - m-2 Sigma i=1  k i u'(xi i ) = 0, u(1) = 0 is studied, where k{ > 0(i = 1, 2,..., m-2), 0  1  2   m-2  < 1. We obtain the existence of at least three positive solutions by using the Leggett-Williams fixed point theorem and the properties.
