# NodeTrail

{% hint style="info" %}
The **`NodeTrail()`** function returns the most recent flowchart nodes (to a max of 20 nodes) that the user passed in current flow.

This function can be used in debugging, allowing you to see the history of steps taken before a certain situation is reached. Every number divided by the "," can be used to search for in the flowchart tab, to find the corresponding node.

This function is SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).
{% endhint %}

{% hint style="success" %}
Returns a <mark style="color:green;">text</mark> that lists up to the last 20 flowchart nodes that the user passed.
{% endhint %}
