DME Query

I'm trying to add a field (EMS-DESCRIPTION) to this DME query in my form, but I get an error when I run it:

function doDME()
{
	var sDME;
	var vCompany = 1;
	var vEmployee = lawForm.getFormValue("txtemployee");
	
	sDME ="?PROD=" + strPDL;
	sDME +="&FILE=EMPLOYEE&FIELD=FICA-NBR-LAST4;FULL-NAME;EMS-DESCRIPTION;EMP-STATUS;HM-ACCT-UNIT;LOCATION.CODE;LOCATION.DESCRIPTION;COMPANY;EMPLOYEE";
	sDME +="&SELECT=COMPANY%3D" + vCompany;
	sDME +="%26EMPLOYEE%3D" + vEmployee;
	sDME +="&OUT=XML";
	//alert(sDME);
	
	var vDMEInfo = top.httpRequest(top.DMEPath + sDME);
	var vObjDMEXML = new top.DataStorage(vDMEInfo);
	var vRecords = vObjDMEXML.document.getElementsByTagName("RECORD");
	if (vRecords.length == 0)
	{
		alert("Employee Not Found!");
		return true;
	}
	var vCols = vRecords[0].getElementsByTagName("COL")
	lawForm.setFormValue("txtficanbr",vCols[0].firstChild.data);
	lawForm.setFormValue("txtfullname",vCols[1].firstChild.data);
	lawForm.setFormValue("txtstatus",vCols[2].firstChild.data);
	lawForm.setFormValue("txtacctunit",vCols[3].firstChild.data);
	lawForm.setFormValue("txtlocationcode",vCols[4].firstChild.data);
	lawForm.setFormValue("txtlocationdesc",vCols[5].firstChild.data);
	lawForm.setFormValue("txtstatdesc",vCols[6].firstChild.data);
	return true;	
}

Any ideas why?

Thanks
