How to get elements in a multi-value field via javascript?

Question

The following will set variables.variable1 to variables.variable2 when the "Script Link" component is clicked...
<Field>
<Display class='Javascript'>
<String>
function myScript() {
el=getElement(document.mainform,"variables.variable1");
el2=getElement(document.mainform,"variables.variable2");
el.value=el2.value;
</String>
</Display>
</Field>
<Field name='Script Link'>
<Display class='Link'>
<Property name='URL'>
<String>javascript:myScript();submitCommand(document.mainform,%20'Recalculate');</String>
</Property>
</Display>
</Field>
My issue is, if variables.variabl2 is a list / multivalued, i get errors trying to traverse through the "array".
How can i read and set an a list element via javascript function above? I've tried things like get() , and variables.variable2[0] .
any help would be appreciated....
is there an API somewhere i can reference?

Hi,
thanks for your reply!
If I have the parameters in the URL and use the method GET it works all right.
but I need the method to be POST. I suppose, I have the wrong way identifying the parameter name
This is from VB
varTarget = "http://localhost:9090/gm/getData" ' getData is my servlet
xmlSendStr = "SQLStmt=SELECT TCPD_Cars.* From TCPD_Cars WHERE (((TCPD_Cars.CarIdent)=45));"
    xmlHttp.Open "POST", varTarget, True   'True means asynchronous
    xmlHttp.Send xmlSendStrthis is part of my Servlet
     protected void doPost(HttpServletRequest request, HttpServletResponse response)
               throws ServletException, IOException {
          response.setContentType("text/html");
          PrintWriter writer  = response.getWriter();
          String SQLStmt = request.getParameter("SQLStmt") ;
        //make the database query and get the returns
        writer.println(GetSQLData(SQLStmt));
        //close the write
        writer.close();                    
     }I would appreciate any suggestions
