My computer are limited, but the way mine works is:
1 - This example uses Google Chrome. It's what I have on my computer. I don't know if it works the same if you use a different system.
2 - At the Camp Moore Home Page, click on "Confederate Burials"
3 - At the burials page, click on "Soldier Search A to Z"
4 - Click on the letter such as N for Norton
5 - At the bottom left of my screen a small block appears which says "Surname_N.mht" and a small caret symbol to the right
6 - Click on the caret symbol and a short list pops up.
7 - Click on "open"
8 - This will switch to Internet Explorer and a spreadsheet with all the "N" surnames comes up.
If you are using something other than Google, it's out of the realm of my computer savvy. If you already use Internet Explorer, it may eliminate a couple of steps.
