Custom Calculations

Have have this custom calculation for shipping.

totalshipping = abs([Shipableitem] == 1) * ([Price] * [Quantity])

How can I subtract all discounts?

Basically I have Free shipping triggered if totalshipping is over $50.00 dollars.

This does not take into account any discounts.

How can I trigger Free Shipping if over $50.00 after discounts?

Here's my Free Shipping Rule:

//eCart Rule
function WAEC_ssdcart_FreeShipping() {
$totalDiscount = 0;
if (true && (($this->TotalColumn("totalshipping") >= 50.00) && ((isset($_SESSION['eCartCheckoutForm_shipping_country'])?$_SESSION['eCartCheckoutForm_shipping_country']:"") == "US") && ((isset($_SESSION['eCartCheckoutForm_shipping_type'])?$_SESSION['eCartCheckoutForm_shipping_type']:"") == "ST"))) {
$totalDiscount += $this->GetShipping();//Result
}
return WA_eCart_FormatNumber($totalDiscount, $this->ForceDecimalsC, $this->DecimalPlacesC);
}
//eCart Rule

Thanks

your free shipping rule is a discount. subtracting all Discounts would also subtract the free shipping discount. that would go into an endless loop.

Discounts cannot be referenced in the calculation.

how are the other discounts set up?

I need more details on exactly what you want to subtract from the Total Shipping calculation.

I have 2 other types of discounts:
Coupons and conditional discounts.

Basically just need to trigger free shipping on the discounted total > $50.00.

Thanks

i need more details on how those other discounts are configured

I've attached my cart object file. Thanks

I going to remove my Free Shipping as a discount and use my flat rate shipping to trigger Free Shipping. This will solve my PayPal issue here: showthread.php?t=29016

So, for Free shipping on the actual Grand Total (After all discounts) I think I need to add another condition.

I tried to add "AND GrandTotal is less then 49.99"

What would the proper syntax be? I tried few variations but no luck..

Thanks

How can I check the GrandTotal from the shipping calculation?

I think you would need to use a custom condition and enter the following code for the condition:
($this->TotalColumn("TotalPrice") - $this->GetDiscounts()) < 49.99
