Ok, I know we have some very good nepali tech experts here in sajha. And I would like some help from them if they don't mind. I have some items I am trying to sell on my website. I have a PayPal merchant account, so I will be using their shopping cart/view cart/buy now buttons, hopefully. But my products are one of a kind products, like paintings. So when I have a customer buy a product, I would like to have either the PayPal button be disabled for that product so that another customer cannot buy it again (since I only have one piece of the product), or even better have the paypal button replaced by a button called "Sold Out". Moreover, instead of making each payment for each item, if possible, it would be better if I could have add to cart button, and then pay for the set of different items. I have the HTML code for the buttons generated by PayPal. I just done know what changed or what addition I need to make there. Any help would be appreciated. For some one who knows HTML or already has a website to sell on line, this should not be too hard, I think. But I am not sure. Thank You again.
