hola,
estoy montando una pequeña tienda con asp y sin DB (solo tiene 7 productos), he adaptado un carrito de la compra muy majo, y funciona bien, hace todas las funciones de añadir producto, eliminarlo, etc. todo en la misma pàgina asp.
el problema es que no esta completo y falta el paso final que es añadir los datos personales del comprador y enviar la info del pedido y los datos del comprador a un e.mail determinado.
alguien podria ayudarme.
Incluyo el codigo
