retrieving AGS data in custom ESS form?

What I'm trying to do is to customize the Open Enrollment welcome screen by reading the BS01 end date for the employee group specific to the user.  I have run a DME query to retrieve the first row of the table and that works fine but when I switch to an AGS call it doesn't allow me to progress to the next function.

Also once the data is retrieved, how is it addressed?  I see several instances in Lawson code where AGS is used to retrun data but I never see where it's stored of addressed.

Here's the AGS call


function getEnrEndDate() 
{ 
 // change to use BS09 so we can be direct to the employee's specific rules
   var obj       = new AGSObject(authUser.prodline,"BS09.1")
   obj.event     = "ADD"
   obj.rtn       = "DATA"
   obj.longNames = true
   obj.tds       = false
    obj.out       = "XML"
   obj.field     = "FC=I"
         + "&BAE-COMPANY="  + escape(authUser.company)
         + "&BAE-EMPLOYEE=" + escape(authUser.employee)
         + "&BAE-RULE-TYPE=A"
    obj.debug     = false
   obj.func = "WelcomeScreen()"
   AGS(obj,"jsreturn")
}
It never gets to the "WelcomeScreen" function I get an object expected message from IE on /lawson/xhrnet/dot.htm.  Below is my iframe setup on the page. (I removed the tag markers because that inhibited the text in the topic display)

iframe name="jsreturn" src="https://inforguru.com/lawson/xhrnet/dot.htm" style="visibility:hidden;height:0px;width:0px;"
iframe name="lawheader" src="https://inforguru.com/lawson/xbnnet/besslawheader.htm" style="visibility:hidden;height:0px;width:0px;"



Anyone have an idea of what's wrong or how to address this?
Thanks in advance
