Problem: Dependent OptionSet Form

i created 2 picklist named "Pays" and "Region" in the lead entity, then i upload the xml file as web resources :

<DependentOptionSetConfig entity="lead" >
 <ParentField id="new_region_fr"
              label="Région">
  <DependentField id="new_departement"
                  label="Département" />
 
 <Option value="100000000" label="Alsace">
   <ShowOption value="100000000"
               label="Bas-Rhin" />
   <ShowOption value="100000001"
               label="Haut-Rhin" />
  </Option>

  <Option value="100000001" label="Aquitaine">
   <ShowOption value="100000002"
               label="Dordogne" />
   <ShowOption value="100000003"
               label="Gironde" />
  </Option>
