If i understand you right, there are two ways!

1. add mv_nextpage like

[set [L]Place Order![/L]]
mv_todo=submit
mv_nextpage=pagename-between-checkout-and-receipt
[/set]

or

2. add a line like

<INPUT TYPE="hidden" NAME="mv_nextpage" VALUE="pagename-between-checkout-and-receipt">

near at this lines e.g.

<INPUT TYPE="hidden" NAME="mv_doit" VALUE="refresh">
<INPUT TYPE="hidden" NAME="mv_orderpage" VALUE="ord/checkout">
<INPUT TYPE="hidden" NAME="mv_order_report" VALUE="ord/report">
<INPUT TYPE="hidden" NAME="mv_failpage" VALUE="special/needfield">
<INPUT TYPE="hidden" NAME="mv_order_profile" VALUE="checkout_profile">

If you "pagename-between-checkout-and-receipt" page is in the directory
..../ord", you must write "ord/pagename-between-checkout-and-receipt".

Make sure, your bank is able to handle the mv session id [data session
id] or it works with cookie!

I hope, this can helps you!
