Hi,

I'm currently having problems applying a 10% members discount for a product that uses Paypal Standard as the payment method.

The discount shows correctly all through the checkout process - but on the final review pane, the hidden Paypal form does not have the correct amount.

I have added a CA with the trigger "Calculate product discounts".

Heres the action:

Title: Apply a discount
Operation: Multiply
Amount: -0.1

Discount type:
Products

Hidden form field on review page:

This should say 8.01....

Has anybody had this problem before? I'm not sure if I should be using an additional CA to calculate the amount at payment stage as well?

Oops, heres the hidden field in the paypal form, which should have a value of 8.01:

<input type="hidden" name="amount_2" id="edit-amount-2" value="8.90" />

I just noticed the correct total is being sent to Paypal.

So to get around the problem I selected "Submit the whole order as a single line item." in admin/store/settings/payment/edit/methods.

Not sure if this is the only way to get around it, looking into uc_paypal.module line 982 it says:

// List the whole cart as a single item to account for fees/discounts

So I'm assuming this is the correct way to calculate discounts with Paypal....

Yes that is a standard method of getting around the "PayPal doesn't like negative numbers" problem. But there is also a patch here:
