### Coupon discount rule

I've got a ecart with a coupon discount applied. What I try to achieve is giving all products with GutscheinCodeArtikel = 1 a 10%
discount. What I've tried is this:

//eCart Rule
function WAEC_eCart_DegustationWeine10() {
\$totalDiscount = 0;
if (true && ((\$this->ConditionalTotal("Quantity", "GutscheinCodeArtikel", "1") > 0) && ((isset(\$_SESSION['GutscheinCode'])?\$_SESSION['GutscheinCode']:"") == "123456"))) {
\$totalDiscount += (\$this->TotalColumn("TotalPrice", "GutscheinCodeArtikel", "1") * 0.1);//Result
}
return WA_eCart_FormatNumber(\$totalDiscount, \$this->ForceDecimalsC, \$this->DecimalPlacesC);
}
//eCart Rule

But this gives me a discount on the Total of all products in the cart not only the one that have the column GutscheinCodeArtikel = 1. How can I sum all products with column GutscheinCodeArtikel = 1?

Thanks for any help

Looks like this solves the problem:

//eCart Rule
function WAEC_eCart_DegustationWeine10() {
\$totalDiscount = 0;
if (true && ((\$this->ConditionalTotal("Quantity", "GutscheinCodeArtikel", "1") > 0) && ((isset(\$_SESSION['GutscheinCode'])?\$_SESSION['GutscheinCode']:"") == "123456"))) {
\$totalDiscount += (\$this->ConditionalTotal("TotalPrice", "GutscheinCodeArtikel", "1") * 0.1);//Result
}
return WA_eCart_FormatNumber(\$totalDiscount, \$this->ForceDecimalsC, \$this->DecimalPlacesC);
}
//eCart Rule
