adding more descriptions and prices to products

Hello forum users, im quite new to zencart, and i have a slight issue with pricing.

1. ok, firstly i do not need help with attributes, as i have added a color choice already.
   now what i need is to add multiple product decsriptions and [B]base[B] prices. e.g

description: QTY
Single Duvet Cover 137x198cm £27.99 [ ] [color]
Double Duvet Cover 198x198cm £38.99 [ ] [color]
King Duvet Cover 229x218cm £42.99 [ ] [color]

                                                      [add to basket box]

i have a good example of this style on the following link, scroll down on the page and take a look:

http://www.homelinen.co.uk/homelinen/Bedlinen/Egyptian-Cotton/Egyptian-Cotton-Bedding-200-Thread-Count_150210.htm

currently my page looks like this:

http://realpurecotton.com/index.php?main_page=product_info&cPath=1&products_id=3

as you can see i have added the color attribute, how do i add this to all the possible product type descriptions as "homelinens" have.

please can you help! i thank you for your time and effort and i look forward to hearing from you very soon

i will try to keep it simple as im sure i`ll confuse you!

ok, i know how to add an attribute to a price. but how do i put on multiple base prices without attributes. i have a good example of this here:scroll down the page and take a look!

http://www.homelinen.co.uk/homelinen/Bedlinen/Egyptian-Cotton/Egyptian-Cotton-Bedding-200-Thread-Count_150210.htm

my own page currently looks like this:

http://realpurecotton.com/index.php?main_page=product_info&cPath=1&products_id=3

as you can see i can only add attributes to one base price. how do i add more with a small description as "homelinen" have?

i thank you in advance for any help you can offer!

You may want to look at the Attribute Grid addon in the Free Addons section.

thank you for your help.

i hae downloaded the add on grid layout and am currently learning to use it.

can i achieve the above effect without adding this module as i am concerned with overriding root files, in case i do not like the end result.

should i go ahead and upload this add on?

thank you
