How do I create this

[rxalex]

I want to create a form that asks for some information when a customer adds an from a certain category into the cart, For example if a person buys eyeglasses, I need the customer to enter a prescription and then this data be transposed into the back end ie. persons order,invoice.

Can this sort of thing be done in Zencart?

Thanks Kenichi, not sure thats exactly what I was looking for... I need a form that pops up or is there another way for a customer to type in information?

Attributes will not make a form that pops up after the customer hits add to cart, but it can perfectly well ask for all the necessary info before the add to cart. There is a "text" type attribute for customer input, as well as several kinds of choice attributes.
