Hello, I am planning to Add Buy Now button to my website. But the thing is that I have price that differs for each users based on some factors. So that means that I can't use default paypal button. I read in PP help that are some HTML variables that I can add to default button code. So I found that there is variable named "amount" <input type="hidden" name="amount" value="Price"> Code (markup): But when I try to add it and test the button - It seems that this code don't work , because if Price is 5 or 10 for example the Paypal page tells me that there is 1 USD to pay. Any ideas how to fix it ? P.S. I've done some research in google and found this article but looks like it does't work now.
