    GB_showCenter('Claim Application form',url,500,600,closeBack);

                if(document.getElementById('txtEmployeeId'))
                {
                        document.getElementById('txtEmployeeId').style.display='none';
                }
                document.getElementById('txtExpenseTitle').style.display='none';
                document.getElementById('txtFwdEmployeeId').style.display='none';


function closeBack(){
            document.getElementById('txtExpenseTitle').style.display='';
            document.getElementById('txtFwdEmployeeId').style.display='';
            if(document.getElementById('txtEmployeeId'))
            {
