How to get cell value from FlexiGrid

[miw002]

I have a flexigrid :\[code\]$('#viewExhibitsGrid').flexigrid({ url: url, dataType: 'json', method: 'get', colModel: [ { display: '<input type="checkbox" class="exhibitCheckBox" id="checkAllExhibits" />', name: 'checkBox', width: 20, sortable: false, align: 'center', process: showDescription }, { display: 'Actions', name: 'actionBtns', width: 60, sortable: false, align: 'center', process: showDescription }, { display: 'ID', name: 'ExhibitID', width: 60, sortable: true, hide: true, align: 'center', process: showDescription }, { display: 'Item #', name: 'ItemNumber', width: 120, sortable: true, align: 'center', process: showDescription }, ],\[/code\]I am trying to obtain the "ItemNumber" column value. (the value's format is : "number-number-number-number" ex: "1-1-1-1"). I am trying to obtain the ItemNumber with this function:\[code\]function getExhibitNum(){ var exhibitNumber = new Array; var i = 0; //$(this).attr('abbr') === 'ExhibitID' $('.exhibitCheckBox:checked').each(function () { if ($(this)[0].id !== "checkAllExhibits" && $(this).attr('abbr') === 'ItemNumber') { exhibitNumber = $(this).children(':first').html(); ++i; } }); return exhibitNumber; }\[/code\]but it's not working. (code is probably wrong but that is why I am here)
