Add Prev/Next Link Text To Product Pages

[lovelygifts]

Hi folks

I'd like to add previous and next buttons so that people can flick through each of the product categories without having to go back to the main sub-category page for the next product. I can find how to add to prestashop but not Thirtybees. It could be the same files but I don't know. Is there a module I can buy or download for free, or would it be possible to add some coding somewhere, if so, where please? 😉

Thanks in advance,
