coldfusion Shop cart Confusion

Hi I am building shopping cart with Micheal's Tutorial Using Arrays and sessions. But i am stuck at the point where i need to store the order details in the database before the payment button is clicked and actually it go to paypal to process the order:

i am doing something like this.

<cfquery name="addOrder" datasource="#application.dsn#">
INSERT INTO orders (o_cust, o_total, o_items,o_quantity,ipaddress)
VALUES (
<cfqueryparam cfsqltype="cf_sql_numeric" value="#logMem.c_id#">,
<cfqueryparam cfsqltype="cf_sql_double" value="#variables.totalprice#">,
<cfoutput>
<cfloop from="1" to="#arrayLen(session.shoppingcart)#" index="i">
<cfif i eq arrayLen(session.shoppingcart)>
<cfqueryparam cfsqltype="cf_sql_varchar" value="#session.shoppingcart.name#">
<cfelse>
<cfqueryparam cfsqltype="cf_sql_varchar" value="#session.shoppingcart.name#">
</cfif>
</cfloop>
</cfoutput>,
<cfoutput>
<cfloop from="1" to="#arrayLen(session.shoppingcart)#" index="i">
<cfif i eq arrayLen(session.shoppingcart)>
<cfqueryparam cfsqltype="cf_sql_varchar" value="#session.shoppingcart.quantity#">
<cfelse>
<cfqueryparam cfsqltype="cf_sql_varchar" value="#session.shoppingcart.quantity#">
</cfif>
</cfloop>
</cfoutput>,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#CGI.REMOTE_ADDR#">)
</cfquery>

if i enter as above it creates only 1 row and enters the info like:

o_items as product1product2 and o_quantity as: 23

and i am unable to identify the products and quantity through database as it looks like item product1product2 has been purchased with quantity 23

can anyone guide how can i do it..

If you can Suggest e database change, Pease reply , I will do that because this is something confusing me last 3 days

Cheers
