I managed to figure it out. After all, I have decades of experience with computer technology. But, I can see how someone who has never used a computer, like many who vote in certain Florida precincts, could have problems. Not to mention poll workers who have no technical knowledge or skills.
Thanks for your informative reply. Of course I was joking. My city uses a bubble sheet and scanner system (you put your filled-out sheet straight into the tabulating machine at the voting center, and get to see the voter count increment on the display). It isn't fully automated, and though it isn't as fun as the old lever voting machines we used to use, it is probably much more efficient.
