# Send Value / String

![TS SendValue](/files/AF9R3OF2noSVabuxwfJR)

With the **LTT Send Value** step type you are able to send one or more **named values** to the station display. We also call those **LTT runtime values**.

{% hint style="info" %}
For send value to work correctly it is important to name the values consistently throughout the whole testplan.
{% endhint %}

Optionally, you can configure one or more of those values as **additional history columns**.

![TS SendValue Hist](/files/YssKRCzbWNkD6Sl36iwN)

To do so, you need to edit the [history configuration file](/ltt/documentation/ltt-gui-manual/configuration/historyconfiguration.md) and add a **custom column** for each runtime value you want to have as a history column.

{% hint style="info" %}
It is important that the custom column name is exactly the same as the value name used in this step type.
{% endhint %}

In combination with history column configuration there are 3 different usage scenarios for LTT runtime values possible:

| Scenario                                                | Outcome                                                                                                                                                                                                     |
| ------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Without custom column entry                             | Values are displayed in [station display](/ltt/documentation/ltt-gui-manual/lttgui/mainwindow/stationdisplay.md) only.                                                                                      |
| With custom column entry                                | Values are displayed in [station display](/ltt/documentation/ltt-gui-manual/lttgui/mainwindow/stationdisplay.md) and [history file](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md). |
| With custom column entry (`ShowInStationPanel="false"`) | Values are displayed in [history file](/ltt/documentation/ltt-gui-manual/lttgui/dialogs/altf10historydata.md) only.                                                                                         |

## 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://docs.irs.systems/ltt/documentation/ltt-gui-manual/teststand/customsteptypes/sendvaluestringvalue.md?ask=<question>&goal=<endgoal>
```

`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.
