eCart not passing Discount to PayPal

We're using ASP/VBScript, DW 8.0.2 and eCart 4.5.2.

We have the following form submitting to PayPal from our view-basket.asp page:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="ourpaypalaccount@ourdomain.com">
<%SFCcart_Index = SFCcart.DisplayIndex - 2%>
<%
while (NOT WA_eCart_EOF(SFCcart))
%>
<%SFCcart_Index = SFCcart_Index + 1%>
<% 'WA eCart Validation
if ((WA_eCart_FormatNumber(WA_eCart_DisplayInfo(SFCcart, "Price") - ((WA_eCart_DisplayInfo(SFCcart, "Price")/WA_eCart_TotalColumn(SFCcart, "TotalPrice")) * WA_eCart_GetDiscounts(SFCcart)), false, 2) > 0)) then
%>
<input type="hidden" name="item_name_<%=SFCcart_Index+1%>" value="<%=WA_eCart_DisplayInfo(SFCcart, "Name")%><%IF WA_eCart_DisplayInfo(SFCcart, "Colour") <> "" Then%>&nbsp;(<%=WA_eCart_DisplayInfo(SFCcart, "Color")%>)<%End IF%><%IF WA_eCart_DisplayInfo(SFCcart, "Size") <> "" Then%>&nbsp;(<%=WA_eCart_DisplayInfo(SFCcart, "Size")%>)<%End IF%>">

<input type="hidden" name="quantity_<%=SFCcart_Index+1%>" value="<%=WA_eCart_DisplayInfo(SFCcart, "Quantity")%>">
<% 'WA eCart Validation
else
SFCcart_Index = SFCcart_Index - 1
end if
%>
<%
set SFCcart = WA_eCart_MoveNext(SFCcart)
wend
set SFCcart = WA_eCart_MoveFirst(SFCcart)
%>
<input type="hidden" name="shipping_1" value="5">
<input type="hidden" name="shipping2_1" value="0">
<input type="hidden" name="currency_code" value="GBP">
<input name="CheckoutButton" type="image" value="Proceed to Checkout" src="stranraer-fc/btn-checkout.png" onmouseover="this.src='stranraer-fc/btn-checkouton.png'" onmouseout="this.src='stranraer-fc/btn-checkout.png'" alt="Proceed to secure checkout" border="0" />
</form>

We have a discount rule set up in our cart to deduct 10% from the sub-total amount, to give us a grand total, but we've noticed that this amount isn't being passed to PayPal. Instead, our form is simply passing the individual product prices to PayPal.

How do we pass the individual items to PayPal whilst, at the same time, passing the correct grand total amount (sub-total - discounts)?

Again, I've attached our view-basket.asp page and cart files.

Thank you.

You can check this out, online, at www.stranraerfcshop.com.

Any ideas though? This is causing us quite a few problems at the moment. Hope to hear from you. Thank you.

change:

<input type="hidden" name="shipping_1" value="5">

to:

<input type="hidden" name="discount_amount_cart" value="<%=WA_eCart_GetDiscounts(SFCcart)%>">
<input type="hidden" name="shipping_1" value="5">

How do I pass charges to PayPal in a similar fashion to how I've passed the discount?

I can't see anything in the PayPal documentation relating to charges, but perhaps I'm looking in the wrong place:
https://developer.paypal.com/webapps/developer/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/

Would appreciate any advice offered. Thank you.

no, poaypal does not offer a way to pass the charges.

you could use the custom element that they offer:
<input type="hidden" name="custom" id="custom" value="<%=WA_eCart_GetCharges(SFCcart)%>" />

Hi Jason,

That's not passing anything to PayPal. Here's my form...

Have PayPal dropped the custom option do you think?
Thanks again.

maybe try using this instead:
<input type="hidden" name="on0" value="Charges">
<input type="hidden" name="os0" value="<%=WA_eCart_GetCharges(BFcart)%>">

I already have an on0 and os0 field. Won't that conflict?

you have on0_<%=BFcart_Index+1%> fields, those are used for passing item options, they include an item index.

using "on0" without an index is used for passing order options.

Ah, I see, sorry. I've just given that a try though and it's not working. When I get to PayPal the on0 and os0 field isn't being picked up.

Kind of worried that this isn't going to be possible yet it's crucial to the operation of this websites' shopping cart application. :o(
Hopefully there will be a way around this! Any ideas?

Much appreciated, as ever.
