<!---
Handle the case where the current cell column is a multiple of 26
1) Need to subtract one from the first lookup (Example: for column 52 (AZ), the formula 52/26 returns 2 which would give us B as the lookup. Subtracting 1 gives us A)
2) Add 26 to the 2nd lookup (Example: for column 52 (AZ) the formula 52%26 returns 0 (which throws an error) Instead of adding to zero, we just make the second reference always the length of the array (26)
