In computing potentials for moduli in for instance type IIB string theory in the presence of fluxes and branes a factorisable ansatz for the ten dimensional metric is usually made. We investigate the validity of this ansatz by examining the cosmology of a brane world in a five dimensional bulk and find that it contradicts the results obtained by using a factorizable ansatz. We explicitly identify the problem with the latter in the IIB case. These arguments support our previous work on this question.
