You can use grids to vary a field based on two other fields, this is very useful for price grids
width = 50, height = 50 => price = 1
width = 100, height = 50 => price = 2
width = 100, height = 200 => price = 12
width = 310, height = 500 => price = 24

The imported grid should look like the grid screenshot displayed above. You can edit the sample file using Excel for example.
You can use this file to test the grid logic
