Allow customer to input custom sizes for product

I'm building a window screen store for my friend and I just can't find anything like this. Maybe I'm searching the wrong terms. Since every customers window size may be different, I need a simple input form that would allow things like how many feet of screen, window dimensions length & width. From what I understand I can't make a product attribute because each order will be different. This info would NOT need to be saved by the website, just included in the email sent to my buddy so he can cut the correct sizes. Any help is appreciated!

So Zencart wouldn't need to calculate pricing based on these dimensions? If not, you should be able to use TEXT attributes for customer input of length and width (wouldn't the feet of screen depend on area?).

No, most products on this are flat rate screens. There are some roll products that are ordered by the foot, these will have to be calculated by the system and charged per foot

Well, I got a text area for Height...but I can't seem to assign multiple attributes. I need Height & Width, but it only let me insert Height in there.

Add a new option name called width as a text box, although wouldn't the chosen product be an indication of width? (I guess only if in a roll...)
Then in the attribute controller add the new option name to the product. Again this is a type in text attribute and the guest could enter any squirrely type data and the price of the item would not necessarily change based on what is entered...
