Hello

I have a customized script of zencart... and my script does the following

$customized_product_total = $currencies->display_price($orders_products->fields['final_price'], 0);


Now my question is ... In my customized product total it does not include gift certificate redemtion amount.. now i want to say
if gift certifcate amount >0 then
$customized_product_total = myprice - gift certificate amoutnt
else
give cerfifcate = 0
$customized_product_total = myprice - gift certificate amoutnt
end if


Thank you for your support..
