Notifications of errors that you might encounter while building and activating a decision tree in Decision Tree Builder enable you to recover easily from errors.

## Error display {#validation-errors-builder__section_fk3_lzc_bxb}

If there are missing values or incorrect configurations in a node or path, errors may appear during validation when saving or activating a decision tree.

The errors are indicated in the following ways:

* Error icons on nodes and paths that have errors
* A label for a count of nodes and paths that have errors in the top-right corner
* An alert message in the side panel showing a list of errors in the selected node or path

{#validation-errors-builder__ul_fbf_zmb_bxb}

For more information on errors and recovery across various nodes and paths, see [Validation errors](https://servicenow-prod.fluidtopics.net/fEIwf14pArMwhNMBl7vmzw "Several types of errors are displayed for missing or incorrect information in the nodes and paths while saving an element or activating a decision tree.").
