ok...so my problem is...i tired switching the characters to different jobs and at first I didnt think that it's important for all the characters to learn magic (or have some magic points). I had the girl do all the mage jobs (white, black, and red) so she got a decent amount of magic points but then I tried to have Luneth be a mage to gain some magic points it seems like no matter how many levels he gains I still cant use any magic. WHY?!!! It just displays a big fat zero...i cant even use the level one magic. What am i doing wrong?

On the status screen where it displays MP it says 0/13 0/2 0/1 0/0 and during battle when i tried using magic it just displays Lv1 0 Lv2 0 HELP!
