[interchange-users@interchange.redhat.com (interchange-users@interchange.redhat.com)]

i'm trying to use a drop down box to select between two pricing options like 
the following:

<FORM ACTION="http://www.yournetflo.com/cgi-bin/foundation/order"; METHOD=POST>
<INPUT TYPE=hidden NAME=mv_order_item VALUE="400979"><select name="400979" 
size="1">
<option value="59.95">$59.95 each
<option value="319.99">case of 6 $319.99</select>
<INPUT TYPE=text name=mv_order_quantity VALUE="" SIZE=3>
<INPUT TYPE=submit VALUE="add to cart">
</FORM>

I can't seem to find how to intagrate the drop down box pricing. can anyone 
help me with this or point me to how to. I have searched the archive with no 
luck.
