Thank you for your reply.
Is it possible to create more than 1 custom tab?
Also, when I create a custom tab from the customization of the single product page, and then add a product, it does not give me an option to input the contents of the custom tab of this specific product. The only way to input data is through the customization of the custom tab at the single product page, and this makes the content general for all products rather than being for a specific product.
Thank you
