- **`Stop`** - Prevent users from entering invalid data in a cell. A Stop alert message has two options: Retry or Cancel.
- **`Warning`** - Warn users that the data they entered is invalid, without preventing them from entering it. When a Warning alert message appears, users can click Yes to accept the invalid entry, No to edit the invalid entry, or Cancel to remove the invalid entry.
- **`Information`** - Inform users that the data they entered is invalid, without preventing them from entering it. This type of error alert is the most flexible. When an Information alert message appears, users can click OK to accept the invalid value or Cancel to reject it.
