Having a paypal calculating VAT issue?

I am developing a simple shopping cart with paypal checkout, but i am stuck with the VAT processing part on paypal's side.
Paypal seems to add up total +VAT+ shipping. But when i substract the VAT from the $grandtotal variable in my shopping cart i get the error message:
The totals of the cart item amounts do not match order amounts.
I am using Paypal's SetExpressCheckout.
My questions:
1/ for parameter PAYMENTREQUEST_0_AMT should i use the total with or without the VAT
2/ should i use parameter PAYMENTREQUEST_0_TAXAMT? if so how do i prevent paypal from adding it up
regards

Please see the following extracts from the PayPal site :
PAYMENTREQUEST_n_AMT - (Required) Total cost of the transaction to the
buyer. If shipping cost and tax charges are known, include them in
this value. If not, this value should be the current sub-total of the
order. If the transaction includes one or more one-time purchases,
this field must be equal to the sum of the purchases. Set this field
to 0 if the transaction does not include a one-time purchase such as
when you set up a billing agreement for a recurring payment that is
not immediately charged. When the field is set to 0, purchase-specific
fields are ignored.
PAYMENTREQUEST_n_ITEMAMT - Sum of cost of all items in this order. For digital goods, this field is required. You can specify up to 10
payments, where n is a digit between 0 and 9, inclusive; except for
digital goods, which supports single payments only.
PAYMENTREQUEST_n_TAXAMT - (Optional) Sum of tax for all items in this order. You can specify up to 10 payments, where n is a digit
between 0 and 9, inclusive; except for digital goods, which supports
single payments only.

AMT = item amt + tax amt + shipping amt + handle amt - discount.
So if your item amt already includes tax, then don't use tax amt, otherwise, make sure item amt doesn't include tax and put tax in tax amt.

Apply Discount to Products in Magento Cart page

I wanted to know how can I give discount value/percentage on cart page for specific product's quantity dynamically via OBSERVER.
Discount can be given on same product's with different quantities.
EX:
Customer add 4 QTY from Product A and I should be able to give 10% discount on 2 QTYs and the discount value should be shown after subtotal (as normal cart rule applied in Magento)
If I can create dynamic cart rule and apply that to products which I wanted that also useful in this case.

this is good link to give discount for order , we can modified for particular product & product qty. calculate discount for different product and its qty. add it and setFeeAmount.

PayPal Charge Tax on shipping (not just items)

I am using the PayPal url approach which works well but when I try charge tax it only seems to apply the tax to the total value of all of the goods, whereas I would like to charge Tax on the Total goods + Shipping, ie
Goods $100.00,
Shipping $20.00,
SubTotal $120.00,
Tax (10%) $12.00,
Grand Total $132.00
This is what I have

I made a change to the tax variable to apply a rate rather than an amount. At this time PayPal doesn't charge tax including shipping as services are typically not taxable.
If this is a requirement I'd recommend calculating the total tax amount on your site before sending the Post to PayPal. The value can be entered in the tax_1 field. I've shown an example of this in the second post.

Here's an example with you calculating the amount. Notice you're only sending one tax amount rather than a tax amount for each item. PayPal doesn't show itemized tax amounts to the customer so there is no impact on the customer's end.

Magento percentage off basket total

Is it possible to have a shopping cart rule that gives the user 25% off the whole total of the basket without using a coupon? It needs to be the total price and not 25% off each product.
Our site is running Magento 1.7.0.2.

Yes, using Promotions > Shopping Cart Price rules you just set it to take 25% off the basket total, and set it to 'No Coupon'.
Shopping cart price rules are rules that effect the total of the cart, not the products individually. Catalog price rules are for individual product discounts.
