Hi Everyone!
I am to figure out a way to symbolize a fishnet with a black and white checkerboard pattern. As a part of my work, I develop grids for activity and every other grid has to shaded to limit activity. Every grid I make is of different size and shape. I have been trying to figure out some type of symbology expression to get this done but haven't quite figured it out.
I got close with numbering the grid cells and using an odd/even function but this doesn't always work.
Any help would be appreciated!
This is what it should look like:

This is what I get with my Odd/even approach
