How a rise in currency value would affect a country's ability to import and export goods?

Well a rise in currency value means that the Country would be able to import the same amount of goods for a lesser price, and exporting goods would be harder as people in other places will have to pay more to you than someone else. So basically if you have rise in currency value Imports goes up and Exports would go down (most of the time) and then if currency goes down it would be the opposite.
