jQuery Grid Plugin - jqGrid

I have a multiselect gridtable with a link below to "save rows". But when I click on that link it doesn't save. I've checked w/ firebug and nothing is being sent... But when I do an alert, the values are there. Obviously I've got something wrong.

note - the ID is text and not an interger

Any hints?

jQuery("#newGrid").jqGrid({
          url:'get.php?q=30'
        , editurl: getr.php?q=31'
        , datatype: "json"
        , mtype: 'GET'
        , loadtext: "Loading..."
        , colNames:['Value']
        , colModel:[
              {name:'thevalue', index:'thevalue', width:198}
        ]
        , sortname: 'thevalue'
        , sortorder: "asc"
        , pgbuttons: false
        , pginput: false
        , viewrecords: false
        , rowList: []
        , height: '100%'
        , multiselect: true
        , pager: jQuery('#newPager')
        , imgpath: '/custom/javascript/jquery-1.2.6/jqGrid/themes/basic/images'
        , caption: 'Experiments'
        , width: "700"
        , height: '100%'
      }).navGrid("#newPager",{search:false,refresh:true,edit:false,add:false,del:false,position:'right'});
      
    jQuery("#makeNew").click( function() {
          var s;
          s = jQuery("#newGrid").getGridParam('selarrrow');
                for (x in s) {
                  var ret = jQuery("#newGrid").getRowData(s[x]);
                  var thevalue= ret.thevalue;
                  alert(thevalue);
                  jQuery("#newGrid").saveRow(thevalue);
        }
    });

thanks
