  We calculate the running of the quark mass and the quark condensate using a
dynamical soft-wall model by Csaki and Reece. We show that a correct running
can be obtained with an appropriate sign for the dilaton field. In the
soft-wall model with quadratic dilaton profile, a wrong sign for the dilaton
field can give rise to a massless vector meson, a signature of spontaneously
broken symmetry in the vector sector, which is not observed in nature. With a
right parameter range, we obtain no such massless vector meson. We also find
that, contrary to the soft-wall model with quadratic dilaton profile, the model
allows a non-vanishing quark condensate in the chiral limit. We obtain the
vector meson mass spectrum similar to that of the hard-wall model. By varying a
parameter in the model we can fit the running of the quark mass and of the
quark condensate.
