What information isn't carrying over? The Sires/Dams Pages look full of data to me. Are you saying it's not calculating properly? Or maybe I'm looking in the wrong place?
Edit: Nvm, I found the problem. It was not your fault, I should have been more clear, and I wasn't... I wasn't thinking, entirely my fault! When you transfer over pages that autofill a bunch of data for you, only copy and paste the data you had to enter, not all the data. For example on the Sires and Dams page, you should have just copied over their names, and let it autofill out their info again, when you copied and pasted everything it deleted the formulas for those columns. Again, it's not your fault, I should have been more clear on that. I had to paste everything back into a new file... I also changed your Fs and Ms (Female and Male) to "Female and "Male" that way it would actually count your male and female foal percentages. I think now that it counts the percentages you'll notice some interesting trends in some of your horses, like Marmato who after 6 foals has only thrown 1 male.
So you didn't do anything wrong by deleting the Win% column, it's designed that you can delete most columns. If you don't intend on using "Lifetime Scores" you can delete that entire page if you want, same goes for the "Scores" column on the Sire/Dam/Prospective Foal pages (since that column takes its info from the Lifetime Scores page).
