This example demonstrates how to use a Sub-Dialog button to update data on the Main Form.

---

## Explanation

The **Main Form** contains two textboxes :one for **Name** and one for **Email**. These fields are disabled and default data is already entered. The **Sub-dialog button**, "Update", will be used to modify the **Name** and **Email** fields on the **Main Form**. The **Sub-Dialog Flow** takes in the **Name** and **Email** from the Main Form. The **Sub-Dialog Form** will display the **current inputs** on the Main form and also has textboxes that users can use to modify the **Name** and **Email**. On the **Update output** path the Flow will output the updated Name and Email data. On the **Cancel output** path there is no output data. If the user updates the data, the changes will be reflected on the Main Form. To test this example, run the **"Main Flow"** Flow.
