<chart caption='NATIONAL PETROLEUM SERVICES' palette='1' animation='1' formatNumberScale='0' startingAngle='125' baseFontSize='15' baseFontBold='1' labelDisplay='rotate'>
<categories>
<category label='40-301' UnitID='20' />
<category label='40-303' UnitID='21' />
<category label='40-305' UnitID='13' />
<set value='' color='#00FF00' />
<set value='4' color='#00FF00' link='EquipmentActive.aspx?EquipmentID=21&Section=2&StartDate=5/25/2014&EndDate=6/3/2014&Status=1&label=40-303' />
/></categories><dataset seriesName='Active'><set value='' color='#00FF00' /><set value='4' color='#00FF00' link='EquipmentActive.aspx?EquipmentID=21&Section=2&StartDate=5/25/2014&EndDate=6/3/2014&Status=1&label=40-303' />

                                Para = Para + "&label=" + ((XmlElement)CategoryLst[j]).GetAttribute("label");
SetElement.SetAttribute("link", "EquipmentInActive.aspx?" + Para);//Error on this line
