Couple of things spring to mind - firstly the creature charmed could be immune to mind affecting spells, in which case, on a failed will save, nothing would happen. Alternatively, you were using a Charm Person spell on something other than a "Person" - a "Person" is any playable race, plus Goblinoids, Monstrous, Orc's or Reptilians. If the target does not belong to one of these racial types, the charm would have no effect.
