Display Data Based On Selected Month From Drop-down List?

I want a table to display data based on which month i select from a drop-down list, the data is of course extracted from a different table. For example, in my final table( highlighted in yellow), i want to display the revenues, cost of goods sold..etc of April in this table when i choose April from the drop-down list, the data of the entire year is located in another table that i plan to hide, as we only need to review one month.
