Scrivener, Index, CreateSpace - Which is First

I finished the book a couple of months ago but am trying to get the darn thing out! I am struggling through the Compile process but am getting there. I am going to index with PDF Index Generator. I will import into CreateSpace for the soft back copies. What comes first? Do I index after CreateSpace import or before? Or does it even matter. These are the kinds of (dumb?) questions that I get hung up on! Thank you to the more experienced users. Steve

What you give CreateSpace is what they will print, so you want to make sure that all of the content you intend to have in the printed volume is in the PDF that you provide. If you want an index in the printed version then you need to take that step first.

Thank you Amber!
