Yes, if I follow you need to edit the information in the "Attributes" section. You can find this within the product page under product options.
Thank you for your reply but sorry I do not follow you. Please advise where you find that information on the products page.
Assuming you're using the standard plugin/themes and not using the Woocommerce version you must:
Go to your dashboard and click products to take you to the product page.
After that scroll down past the bit where you write stuff and you will see a section called product options.
To the left of this section are various tabs, general, attributes, shipping, supplier, gallery, SEO etc.
Click the attributes one and you can edit them.
Hope this helps.
