# Using Arguments

> Use arguments in Studio with Invoke Workflow File and Launch Workflow Interactive activities to pass data between workflows.

Due to the nature of arguments, you are going to use them a lot in relation with the **Invoke Workflow File** and **Launch Workflow Interactive** activities. They can be found in the **Activities** panel, under **Workflow > Invoke** and they enable you to browse for a project, and import and edit their arguments.

## Example of Using an Argument

To exemplify how to use an argument in an automation with an **Invoke Workflow File** activity, we are going to create two separate sequences. A very simple one in which to assign a value to an argument, and a second that invokes it and displays the value in a message box.

1. Create a new sequence.
2. In the **Arguments** panel, create an argument, `out_StoreValue`.
3. From the **Direction** list, select **Out**, and do not change the **Argument Type** from **String**.
4. Add an [Assign](https://docs.uipath.com/activities/docs/assign) activity to the **Designer** panel.
5. In the **Properties** panel, in the **To** field, add the `out_StoreValue` argument.
6. In the **Value** field, type a string, such as "How does one use an argument?".
   
   The first project should look like in the screenshot below.

7. Create a new sequence.
8. Create a string variable, `FinalValue`.
9. Add an [Invoke Workflow File](https://docs.uipath.com/activities/docs/invoke-workflow-file) activity to the **Designer** panel.
10. On the activity, select the **Browse (…)** button and browse for the previously created sequence.
11. Select **Import Arguments**. The **Invoked Workflow’s Arguments** window is displayed. Note that the argument of the first sequence is displayed here.
12. In the **Value** field, add the `FinalValue` variable and select **Ok**. The argument is imported and the value from it is going to be stored in the current project through the `FinalValue` variable.
13. Add a [Message Box](https://docs.uipath.com/activities/docs/message-box) activity under the **Invoke Workflow File**.
14. In the **Properties** panel, in the **Text** field, type `FinalValue` + " This is how", for example.
   The second automation should look like in the screenshot below.

15. Press Ctrl + F6 in the second sequence. The automation is executed correctly and the message box displays the desired text.

### Result

The automation runs successfully. The message box in the second workflow displays the text assigned to the argument in the first workflow.
