Submitting a javascript object to vbScript and referencing its properties in classic ASP

I’ve never passed a JavaScript object to an .asp page. Can someone give me the syntax here. I’ve tried googling w/o success. The object is called buyerInfo. Using jQuery.

<form id="aform" action="formact.asp" method="POST">
    <input type="hidden" id="myhid" name="myhid" value="">
    <input type="submit">
</form>

<script>
    buyerInfo = {};
    buyerInfo.name = "Joe Buyer"
    buyerInfo.zip = "12345"
    $("#myhid").val(buyerInfo);
</script>

— and in formact.asp

<%
    Set buyer = Request("myhid")
    name = buyer.name
%>

yields
Object doesn’t support this property or method: ‘buyer.name’.

What is the correct way to reference these? I know the JavaScript object is being passed, but I don’t know how to access its pieces. Thanks.
