If either the “Month” or “Type” columns are blank, it will display all the details.
If the “Month” column is not blank, it will display the details from “Transportation” table only if the selected “Month” matches the value in the “Filter Transportation” table.
If the Month" column is not blank and “Truck Type” column is not blank, it will display the details of the selected “Month” and “Truck Type” matches any of the values in the “Filter Transportation” table.
But it seems my formula is not correct. It only meets the first 2 conditions.
When i enter a value in “Month” and “Truck Type” column it only filters according to “Month” it does not filter according to “Truck type” as well.
