The cache was initially listed as a small but it has been changed to a micro. I've had to change the pod due to flooding.
Note that the puzzle is a grid with nine rows and columns. There are also nine 3X3 boxes. Simply complete the grid so every row, column and 3X3 box contains every digit from 1 to 9. Each digit can only used once in each column, row and 3X3 box. See the attached picture labeled "Example" for a partially completed grid.
The coordinates for the cache are: N32 AB.0CD and W097 0E.FGH
The numbers for A,B,C,D,E,F,G and H are the numbers you assigned to the corresponding spaces in the grid.
