I have a table called shoppinggift registry which stores the items users adds as gifts
and includes these fields:
productID,Quantity,UnitPrice

I have another table called shoppingCart and as the name says it stores the products of stores which are added to shopping cart
fields are:orderID,productID,price

Now i have output the table to show for ex all the gifts of user A on the page
for ex he has 3 gifts
how can I add these records on the next page(when user clicks checkout) to the shopping cart
if it was 1 records i could use a hidden ID field but now these are more than 1 field

here is the page:
set RsReg=server.createobject("adodb.recordset")
RsReg.open "select P.productID,P.productName,R.productID,R.regID,R.un itPrice,R.amountRemain,R.Quantity from Shop_registryItems R left outer join Shop_Products P on R.productID=P.productID where regID=" & intID ,Conn,0,1


if rsReg.eof then
%>
<table class=err align=center>
    <tr>
    <td>
    <p align="center">item does not exist</td>
    </tr>
</table>

<%
  response.end
   end if


 session("userGiftRegistryID")=rsReg("regID")
%>
       <br>
  <form action="checkoutRegistry.asp" method="post" id="form1" name="form1" >
 <table class=subnav2 align=center>
     <tr bgcolor="#ff9900">
 <td width="44%" align="center" valign="center" ><strong>Product Name<strong></strong></strong></td>
 <td width="22%" align="center" valign="center"><strong>Quantity<strong></strong></strong></td>
 <td width="23%" align="center" valign="center"><strong>Unit Price<strong></strong></strong></td>
 <td width="25%" align="center" valign="center" ><strong>Balance Remaining<strong></strong></strong></td>
 <td width="15%" align="center" valign="center" ><strong>Quantity<strong></strong></strong></td>
 <td width="25%" align="center" valign="center" ><strong>Partial Purchase<strong></strong></strong></td>
 </tr>


<%

   while not RsReg.EOF

   intProdID = RsReg("productID")
%>
<input type=hidden name=pid value="<%= rsReg("productID") %>">

<tr>
            <td width="15%" valign="center" align="left" nowrap> <%= rsReg("productName") %></td>
            <td width="22%" align="center">&nbsp;<%= rsReg("quantity") %> </td>
                <td width="23%" align="center">&nbsp;<%= rsReg("unitPrice") %>$ </td>
                <td width="44%" align="left">&nbsp;<%= rsReg("amountRemain") %>$ </td>
                <td width="16%" align="center">
                         <input name="quant<%= intProdID %>" size="3" value="1" class=field>$
                </td>
                <td width="25%" align="right">
                        OR $<input name="quant<%= intProdID %>" size="3" value="" class=field>
                </td>
            </tr>

RsReg.Close
set RsReg = Nothing

Build a redirect statement
dim moveon
moveon=nextpage.asp?user=

response.redirect(moveon)+username+"&pid="+pid.... ....
or you can simple use multiple hidden values in HTML and request all of them on the next page...either way should work.
