### Review the Formula

### Implement the Formula in Action

* Create a **new account**.
  * The **account code field** is automatically updated using the mobile number and account code formula.

* Save the account and then reopen it.
* Modify the **mobile number**.

As you’ll observe, when the mobile number is updated, the **account code is also refreshed automatically** with the new details.
