[ic] static page

[interchange-users@interchange.redhat.com]

i'm trying to set up multiple items on a static page but i'm having trouble 
with the options. I'm trying to use the following:
<FORM ACTION="http://www.airdelights.net/cgi-bin/foundation/order" 
METHOD=POST>
<INPUT TYPE=hidden NAME=mv_order_item VALUE="400979">
<INPUT TYPE=hidden NAME=mv_sku VALUE="400979
<SELECT NAME="mv_sku"><OPTION VALUE="400979-319.99">AutoFresh Select Aerosol 
Dispenser - 319.99 ($319.99)<OPTION VALUE="400979-59.95">AutoFresh Select 
Aerosol Dispenser - 59.95 ($59.95)</SELECT>
<INPUT TYPE=text NAME=mv_order_quantity VALUE="">

I can get one item to work properly but when I try to add a second item it 
mixes the two together in the basket?  any suggestions?  is the mv_sku the 
wrong thing to use here?  should the options be set up with <INPUT 
TYPE=hidden NAME=mv_options?
boy any help would be great, I've been stuck on this for days.
