you won't see the check toggles until the class type has been set to Prestige on the first tab -- this boggled me for a while too, but you have to do that first. Prestige classes are the only ones that can have this type of spellcasting.
I have it on Prestige, the requirements magical tab has everything grayed out (don't know why) The spellcaster tab shows the levels 1 -20 and spell level 1-9 on the spells per day box. No "check" box. I put a "0" in the "0 level" spell slot for 1, 3, 5, 7,and 9 is this right?
I had the "class can cast its own" box checked. Big no no. Once I unchecked that box I saw what you were talking about. Thanks for the help. Your a real credit to the community!
Well that's just not right. So let's go back to the beginning.
What version of ET Helper do you have installed? (Go to Help, About). You should have version 0.60. If not, then that's your problem -- earlier versions didn't support this feature.
The only two tabs that matter are the General tab, where you select Type of Class -- Prestige, and the Spellcasting Tab, which should look like the attached screenshot:
Gee, just call me "Johnny-come-lately". I'm glad you got it figured out. And yes, there are two requirements to see that checkbox: It must be a Prestige Class (only they can add to other spellcasters) and it must not be able to cast it's own spells (or else it would have its own progression and not be changing another class's).
