I changed the file
/customer/main/cart.tpl
{if $cart.coupon_discount eq 0 and $products ne ""
and $membership_levels ne "Wholesale"}
<P>
{if $active_modules.Discount_Coupons ne "" }
{include file="modules/Discount_Coupons/add_coupon.tpl"}
{/if}
Coupon still shows up, no matter who is signed in.
PLEASE HELP!!!
Thanks
