DistanceMatrixService array
===

I am trying to use the google.maps.DistanceMatrixService.
If I have an array of stores,
It does not seem like I can directly pass it into 
destinations: []

Instead of passing
destinations: [stores[0], stores[1]]

Maybe this cannot be done?
Maybe I am doing it wrong?
Anyone have ideas?

thanks

      var store1 = "2245 South Shore Ctr Alameda CA 94501"  ;

      var stores = [];
      stores[0] = "1041 Summit Avenue Oconomowoc WI 53066";
      stores[1] = "4081 N Oakland Avenue Shorewood WI 53211";    
      
      function calcDistance() {
          service = new google.maps.DistanceMatrixService();
          service.getDistanceMatrix(
          {
              origins: [store1],
              destinations: stores[],
              travelMode: google.maps.TravelMode.DRIVING,
              unitSystem: google.maps.UnitSystem.IMPERIAL,
              avoidHighways: false,
              avoidTolls: false
          }, 
          callback
      );
      }
