# Hidden Setting for Line Item Editor Columns
The Hidden Setting for columns in the Line Item Editor is primarily used for the following scenarios:
**Handling Field Values for Calculations**
When specific field values are required for advanced calculations, these fields must be included in the Line Item columns. However, users may not need to see all of these fields on the screen. By using the hidden setting, these fields can be excluded from display while still being available for calculations.
**Preventing Formula Field Errors**
Formula fields in the Line Item object are recalculated during save operations. If a formula depends on a field with a null value, it may result in an error. To prevent this, the hidden setting ensures that required fields are added to the columns and assigned appropriate values without being visible to users.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.smallbuilder.com/smallbuilder-line-items/builder/builder-setup-steps/setup-line-item-editor/hidden-setting-for-line-item-editor-columns.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
