Hello, the exchange rate in usd is blank and so we cannot save transactions. how can this be rectified?

Hello, precious. 

When dealing with foreign currency transactions on QuickBooks, it is important to note that exchange rates are used to determine the values of your home currency. However, if you prefer to use your own rate for multiple transactions, you have the option to update the rate in your currencies list. This way, you can customize your transactions to suit your individual needs and preferences.

Here's how: 

1. Go to the Gear icon, then choose Account and Settings.
2. Select Advanced.
3. In the Currency section, select Edit.
4. From the Home Currency ▼ dropdown, Find the exchange rate you want to update.
5. Click Save.

After you save the changes, the currencies list will display the updated exchange rate, along with the date and time of the update and the person who made the change. For additional information, please check out this article: Enter an exchange rate. This resource also explains in-depth how the system computes the exchange rate.
