Error on the Materia Play Guide

I'm not sure where to post this but I found a small error I think while reading the Materia guide here

http://lodestone.finalfantasyxiv.com/pl/guide/materia01.html

When scrolling down to the "Materia Melding" section, it says here
* You must have a minimum of one Disciple of the Land class, excluding culinarian and alchemist, at level 18 or higher for this quest to be available.

Though I believe it should be Disciple of the hand and not the land. Just pointing it out.
