'Define these variables.
Dim apikey
Dim listid
Dim MCURL = "http://api.mailchimp.com/1.2/"

Function listSubscribe (strEmail, strFirstName, strLastName, strPhone)
    Dim resp
    Dim merge_vars
    Dim ParamArr

    Set merge_vars = Server.CreateObject("Scripting.Dictionary")
    With merge_vars
        .Add "OPTINIP", Request.ServerVariables("REMOTE_ADDR")
        .Add "double_optin", False
        .Add "FNAME", strFirstName
        .Add "LNAME", strLastName
        .Add "phone", strPhone
    End With

  'Function Reference: listSubscribe(string apikey, string id, string email_address, array merge_vars, string email_type, boolean double_optin, boolean update_existing, boolean replace_interests, boolean send_welcome)
  'NOTE THAT EMPTY VALUES DO NOT WORK WELL WITH THIS VERSION OF XLMRPC.ASP. BEST TO SEND EMPTY STRINGS.

    'ParamArr = array(apikey,listid,strEmail,merge_vars,"",True,True,True,True)
    ParamArr = array(apikey,listid,strEmail,merge_vars,"",True,True,True,True)

    resp = xmlRPC(MCURL,"listSubscribe",ParamArr)
    'Uncomment below for Error Checking
    Response.Write(Session("xmltxt")&"<br>")
    Response.Write(Session("ServerResponseText")&"<br>")
    LGNListSubscribe = resp
End Function
