### Resolution

This occurs if you have added an element with a custom code but deleted the custom code class afterward. for instance, **LACCustomCode3**.

#### Version 4.1.x.x and Later

In the LAC class **LACValueSource_CustomCode** / **newCustomCode** uncomment the line with the missing **LACCustomCodeX**.

#### Older Versions

1. In the LAC class **LACValueSource_CustomCode** / **construct** uncomment the line with the missing **LACCustomCodeX**.
2. Save and compile only that class.
