I want to push elements to 2D array,

My code is,

        var results = [];
        var resultstemp = [];
        function bindlinks(aamt,id1) {
        resultstemp=results;        
            imagesArray.push($("#image1").mapster("get"));

            if(results.length==0)
            {
            results.push([id1]);    

            }
            else
            {
               var ck=0;
               var lng=results.length;
                for (var i = 0; i < lng; i++) {

                  if(results[i]==id1)
                  {


                    ck=1;
                     results = jQuery.grep(results, function(value) {
                        return value != id1;
                      });

                  }                                     
                }                   
                if(ck==0)
                {
                results.push(id1);                  

                }                   
            }

I want to push id as well as aamt to array. Here i am pushing only id to array. I am not sure about how to add aamt to second position in 2D array.

Help me please,

Thank you
