Checkout Wizard form variables not saved to database

Some of my variables set in the 'Store Cart Summary in Database' on the confirm.asp page are not being saved to the database. It appears that all the variables that are taken from the form on the checkout.asp page are being passed through to and displaying correctly on the confirm.asp page but not saving to the database when the customer confirms the order. I have checked the entries and they appear to be correct:

OrderID
OrderReferenceID <%=Session.SessionID%>
OrderVisitorID
OrderShipping <%=WA_eCart_GetShipping(ts08usa)%>
OrderTax <%=WA_eCart_GetTax(ts08usa)%>
OrderTotal <%=WA_eCart_GrandTotal(ts08usa)%>
OrderDate
OrderShipAddress1 <%=cStr(Request.Form("shipping_street1"))%>
OrderShipAddress2 <%=cStr(Request.Form("shipping_street2"))%>
OrderShipCity <%=cStr(Request.Form("shipping_city"))%>
OrderShipStateID <%=cStr(Request.Form("shipping_state_province"))%>
OrderShipZip <%=cStr(Request.Form("shipping_postcode"))%>
OrderShipCountryID <%=cStr(Request.Form("shipping_country"))%>
OrderStatus


Also, certain variables are not being sent on the email receipt which I have used Universal Email to do for me during the checkout wizard process. The variables not going to email are the Order Number and the credit card information. However, strangely, the shipping details not being saved to the database are making it to the email receipt.

Hope you can help
