in-commerce checkout issue

Imported From: http://groups.google.com/group/in-portal-bugs/browse_thread/thread/a49e33e1594c47d3#

                        <form method="POST"
action="<inp2:ord_GetFormAction/>">
                                <inp2:ord_GetFormHiddenFields
return_template="in-commerce/checkout/checkout_success"

cancel_template="in-commerce/checkout/billing" />
                                <inp2:m_if
check="ord_NeedsPlaceButton">
                                        <input type="submit"
value="<inp2:m_Phrase label="lu_order_CompleteOrder" />"
class="button">
                                </inp2:m_if>
                        </form>

I'm assuming that the submit will be redirected to either
return_template or cancel_template but neither is happening.
