Sort Attributes by number?

[Blueskidoo]

Hi!

I am a new user, and I managed to set up Prestashop (which is a testament to how easy it is to use!) So thanks for all the work you guys have done.

Many things I sell are sized and I'd like to be able to sort the attributes so they come up in numerical order smallest to largest in the front office.

How do I do that?

Thanks so very much!
