jQuery Grid Plugin - jqGrid

I have this function to establish my JqGrid.

$('#_visitorLogGrid').jqGrid({
        caption: paramFromView.Caption,
        colNames: ['FundDocLineID', paramFromView.Dodic, paramFromView.Line_Item, paramFromView.Orig_RDD, paramFromView.Fiscal_Year, paramFromView.FMS_Case],
        colModel: [
                    { name: 'FundDocLineID', index : FundDocLineID}, //width: 20, hidden: true, key: true },
                    { name: 'Dodic', index: 'Dodic', width: 300 },
                    { name: 'LineItem', index: 'LineItem', width: 150 },
                    { name: 'OrigRDD', index: 'OrigRDD', width: 150/*, formatter: datefmt*/},
                    { name: 'FiscalYear', index: 'FiscalYear', width: 120},
                    { name: 'FMSCase', index: 'FMSCase', width: 70, align: "center" }
        ],
        hidegrid: false,
        pager: jQuery('#_FundDocsEditPager'),
        sortname: 'FundDocLineID',
        rowNum: paramFromView.PageSize,
        rowList: [10, 20, 50, 100],
        sortorder: "asc",
        width: paramFromView.Width,
        height: paramFromView.Height,
        datatype: 'json',
        caption: paramFromView.Caption,
        viewrecords: true,
        mtype: 'GET',
        jsonReader: {
            root: "rows",
            page: "page",
            total: "total",
            records: "records",
            repeatitems: false,
            userdata: "userdata"
        },
        url: paramFromView.Url
    }).navGrid('#_visitorLogPager', { view: false, del: false, add: false, edit: false, search: false },
       { width: 400 }, // default settings for edit
       {}, // default settings for add
       {}, // delete instead that del:false we need this
       {}, // search options
       {} /* view parameters*/
     ).navButtonAdd('#_visitorLogPager', {
         caption: paramFromView.DeleteAllCaption, buttonimg: "", onClickButton: function () {
             if (confirm(paramFromView.DeleteAllConfirmationMessage)) {
                 document.location = paramFromView.ClearGridUrl;
             }
             else {
                 $('#_visitorLogGrid').resetSelection();
             }
         }, position: "last"
     });

However it is currently failing at line 7 column 5 with FundDocLineID is undefined.  I copied this code right out of the example at http://www.codeproject.com/Articles/594150/MVC-Basic-Site-Step-jqGrid-In  I altered it accordingto code at http://blogs.teamb.com/craigstuntz/2009/04/17/38229/  But the error persists.  (Interestingly enough the first code yesterday yielded object undefined at that location. Now the error has changed.)

Can someone point out where I went wrong?
