Exchange Rates Screen
This screen allows you to set the exchange rate between two currencies. It will display the exchange rate history and allow you to add or update specific exchange rates. Select the "From" currency and the "To" currency from the drop down menus, and enter the current exchange rate.
Clicking the [Enter New Rate] button next to existing exchange rates will set the "Update Exchange Rate" form to match the appropriate currencies, so that you can enter a new exchange rate for existing entries.
Clicking the [Update] button in the "Update Exchange Rate" form will update the existing exchange rate or create a new exchange rate entry.
