   void DispatchTheClick(PA_PluginParameters params)

      PA_AreaRect   r = PA_GetAreaRect(params);
      short         x, y;
 
      PA_GetClick(params, &x, &y);
      if( y < = (r.fBottom - r.fTop)/2 )
         DoClickInUpZone(params);
      else
         DoClickInLowZone(params);
   }

Error Handling
