Size attributes

[owas]

Hi,

I have my products on the site, and now I need to add the size option. So my cvs for the size attribute import, has two columns, in one is this,

Size:Small 0 6 months, Medium 6 12 months, Large 12 18 months, X Large 18 24 months

and the next column products ID.

So then I go to import in BO, Select combinations, my file cvs file, then I choose ID, and options and import. I then get a message saying name is empty for default language, and the cvs file has been imported. But the size option is not showing with the products??

I know this has been coved a lot here, but I have been at this for three days and could really do with getting this sorted.
thanks

I can create the attributes, then I need to import them into my catolgue So I create a cvs file with two columns, one with size:0-16 months, 6-12 months and the other with the product ID which is already asociated with each product.
So then to import this cvs file, once in import, I select the cvs file, select and then import, product ID and options. Yet this still wont import the sizeing option?
