  We study the cosmological evolution of two coupled scalar fields with an
arbitrary interaction term V_T(\phi,\vp) in the presence of a barotropic fluid,
which can be matter or radiation. The force between the barotropic fluid and
the scalar fields is only gravitational. We show that the dynamics is
completely determine by only three parameters L_i i=1,2,3. We determine all
critical points and study their stability. We find six different attractor
solutions depending on the values of L_i and we calculate the relevant
cosmological parameters. We discuss the possibility of having one of the scalar
fields as of dark energy while the other could be a scalar field redshifting as
matter.
