PHP Code:
formatex(Item, charsmax(Item), "%L", LANG_PLAYER, "NEXT");
menu_setprop(Menu, MPROP_NEXTNAME, Item);
// Etc.
However you're using
LANG_PLAYER incorrectly. It's only used in natives which send text to all the players in the server. In this case, you should replace
LANG_PLAYER with player's ID.
