I placed an Add to Cart pay pal button on my website. In paypal it allows you to customize your button. When I use the customize button to indicate sizes and dimensions of my art, it will allow me to do so, but when I test it with paypal it only takes one size which is my small size. It gives me an error message from paypal, "error with website, please contact seller" I contacted paypal to discuss. They stated to me that once the codes are placed on my site it becomes encrypted and they can not view for any errors. They showed my what they are seeing and they ask if you will remove the encryption so they may see - possible reasons why it would only take the size small and not any other. This has to be done by you. Please view my website www.wallfashionsva.com under the Framed Art Finishes tab for testing. When you click on a size larger than small you will receive an error.
