# Returning Multiple Values in Truth Tables

## Overview

Truth Tables can be configured to return more than one outcome, which is helpful when there is a single set of data that a developer may need to be analyzed in multiple ways.

The result of the Truth Table will be outputted as a list of objects.

## Example

This example will explore creating a basic **Truth Table** that takes in the age of an applicant to return multiple true/false evaluations based on the criteria configured.

The Truth Table will show whether the applicant is able to rent a car, whether a Young Driver fee is applied, and the estimated cost per day is.

1. [Create a Truth Table.](https://documentation.decisions.com/version-10/docs/creating-a-truth-table) When the **Data Definitions** window appears, define an input as **Age** and set the **Type** to be **Int32**, then close the **Data Definitions** window.
2. Click **[Select Data Element]** and pick **Age** from the list, then click Close.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781707919249.png)
3. The **Pick Verb** window will open automatically, select **Between** from the **Number Rules** section and then click Close.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781707942009.png)
4. Hover over the top **Default Output Data** cell and click the pencil icon when it appears.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781707962538.png)
5. Replace **DefaultOutputData** with **Can Rent** for the **Name** field then click OK. Leave **Boolean [Logical]** as the **Type**. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781707985300.png)
6. Click the plus icon to the right of the **Can Rent** cell. Define this new Output Data with the name **IsYoungDriver** and **Boolean [Logical]** as the **Type**, then click OK. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781708187575.png)
7. Repeat the above steps to create a new output column with the name **CostPerDay** and **Int32** as the **Type**, then click OK.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781708060809.png)
8. Now that the outputs are configured, define three separate rows for testing, as shown below![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1781708225511.png)

## Debug

1. Click the **Debug** button on the top **Action Bar** of the **Rule Designer**.
2. Under the **Default Inputs** section, define the **Age** as **23**, then click **Run Capturing All**.  
  
The Truth Table will evaluate the input data. The output will evaluate whether they are able to rent a car, if they are a young driver, and their estimated cost per day is 45.
