Hi, I'm having a strange issue and I need some help resolving it
I have design a complete CFM shopping cart with auto generate discount coupon 
and lots of other features however a small thing still generate a major issue

using + / - sign the customer can increase or decrease the ordered quantity of 
a particular item

it is working fine when only 1 item is on the shopping cart if several item are 
in it
increasing or decreasing the value of 1 of them will effect the all product 
quantity in the cart

where am I wrong

   <cfelseif Isdefined ('FORM.plus_button.y')>
    <cfloop from="1" to="#ArrayLen(SESSION.cart)#" index="i">
         <cfset SESSION.cart[i].quantite = 
#IncrementValue("#SESSION.cart[i].quantite#")#  />
    </cfloop>
 <cflocation url="contenu_commande.cfm">

      <cfelseif Isdefined ('FORM.moins_button.y')>
    <cfloop from="1" to="#ArrayLen(SESSION.cart)#" index="i">
     <cfset SESSION.cart[i].quantite = 
#decrementValue("#SESSION.cart[i].quantite#")# />
               <cfif SESSION.cart[i].quantite LTE 1 >
                  <cfset SESSION.cart[i].quantite = 1 />
                   </cfif>
    </cfloop>
 <cflocation url="contenu_commande.cfm">

Thank you for your help
Marc
