Spells Creation Question

[Melandril]

I'm not sure which part of the forums to ask this question, so, I'll ask it here.

When creating a new spells, how do I get a new spell into a player's spell book?

Not finding a table that held this information I:
1) Created the spell based on the existing (BLpet85) only I changed the classes15 to 255 and classes2 to 2 (I think this means lvl2 clerics can use the spell)
2) I then created a new item based on the Yaulp V scroll and changed the name to my new spell and the scrolleffect to the ID of my new spell
3) I then put 1 copy of the scroll item into my character's inventory
4) I did not update spells_us.txt (just had someone suggest that in another spot)
5) the result was the scroll was created, had the new item name, I think it held the Yaulp V description and was listed only as CLR(255)


is there a way to get new spells directly into a player's spell book? and other than step 4, how do I get the scroll to have the right description and level to scribe?

Thanks
