Yet More Mod Questions

[tinkthank]

Argh, can someone tell me what I am doing wrong?

I am making the national summons, and already modded the Carrion Centaur 714 unit appropriately (works fine when I make him recruitable, which I did just to test, because I cannot summon him), but I cant get anyone to cast the darn spell. It will not show up in the list of spells that people can cast.

#selectspell "Carrion Centaur"
#school -2
#path 0 1
#path 1 0
#pathlevel 0 1
#pathlevel 1 1
#fatiguecost 300
#end

Thanks much in advance.
