# Sample database search script

> Sample web custom action script that searches a data set from the FlexiCapture Web Verification Station and copies the found value into the current field.

This sample script searches a data set from the Web Verification Station and copies the found value into the current field.

## Create a data set

Before you configure the script, create a data set for it to search:

<Steps>
  <Step title="Open the document definitions">
    Open the Project Setup Station and click **Project → Document Definitions**.
  </Step>

  <Step title="Add a data set">
    Click **Document Definition → Document Definition Properties**, open the **Data Sets** tab, and click **Add**.
  </Step>

  <Step title="Create records">
    Create a data set, add a few records, and click **Close**.
  </Step>
</Steps>

You add this script as a user script for the Web Verification Station. For more information, see [User scripts for the Web Verification Station](/flexi-capture/appendix/scripts/web-custom-action-script).

## Sample script

You can also find this sample script at `https://<ApplicationServer>/FlexiCapture12/Verification/Scripts/CustomScripts/customActionLookup.js`, where `<ApplicationServer>` is the name of the computer where the Application Server is installed.

Replace the values in these lines:

* `var dbCacheName = 'DataSet1';` — `DataSet1` is the name of the data set you created.
* `var fieldNameInCache = 'Field2';` — `Field2` is the name of the data set field that contains the value to copy.
