Like the build button but uppgrades instead.

[Giho]

I wonder how to make a button in a bulding, so when u click on it new slots with upgrades comes, so u can chose between more uppgrades. And thats because i would like to have multiply upgrades in a building , instead of 8 buildings. I have seen sort of solution to this on a map called EotA Twilight. But they use items and there are no go back button. I would like to have it more like the build button for peon.
All help are pleased.

3 Words, Spellbook

Spellbook's one word, not three... you aren't supposed to count the "three words" part.

Anyway, what he said... when the ability in the Spell Book is used, use triggers to perform the research.
