I figured out that for some reason, you can't set values at 0 indexes. So I began using the X index of 1 to store which save file would be accessed. At this index, 1 = save file 1, 2 = save file 2, etc.
And I thought I could use the Y index as a "subfolder" of sorts, since you can store values at X, Y. I was going to make the first Y index store Health, for example. So 1, 1 would store save file 1's health. 2, 1 would store save file 2's health. 3, 1, you get it...
But apparently, for some reason, I couldn't use the value of 1 for the index of Y. For some reason, it treated y1 as x1. When I tried to store the variable of Health in x1, y1, it ended up being stored in x1 alone. So it had to be put in 1, 2. I couldn't use the index of 1 for the Y coordinate for some reason. Is it supposed to be like that?
