Is this line? Looks empty...
No, we're looking for byte 686 (in decimal number notation), and it is a single byte. I cut and pasted from the spreadsheet (I expected you to refer to it directly, actually). The 1 was from a different box, saying that the data is 1 byte in size.
Since it looks like your hex editor shows offsets in hexidecimal, search for offset 2AE.
Sorry for the confusion.
