AGS C

What's wrong with this AGS call? Line change is not working:

function agsHR20(ContactType, seqNbr, wkphonenbr, wkphoneext, effdate, lineFc) {
    var agsObj = new AGSObject(authUser.prodline, "HR20.1");
    agsObj.event = "CHANGE";
    agsObj.rtn = "MESSAGE";
    agsObj.longNames = "ALL";
    agsObj.tds = false;
    agsObj.field = "FC=C"
+ "&PT-XMIT-NBR=1"
+ "&PT-DATE=21981231"
+ "&PT-SEQ-NBR=" + escape(seqNbr,1)
+ "&HCN-COMPANY=" + parseInt(authUser.company, 10)
+ "&HCN-EMPLOYEE=" + parseInt(authUser.employee, 10)
+ "&HCN-CONTACT-TYPE=" + escape(ContactType,1)
+ "&HCN-SEQ-NBRr0=" + escape(seqNbr,1)
+ "&HCN-EFFECT-DATEr0=" + escape(effdate,1)
+ "&HCN-PHONEr0=" + escape(wkphonenbr,1)
+ "&HCN-PHONE-EXTr0=" + escape(wkphoneext,1)
+ "&LINE-FCr0=" + lineFc
    
agsObj.func = "parent.DisplayMessage()"; 
    agsObj.debug = false;

Thank you.
