This Example Lab demonstrates how the "Runtime Selection" setting works on a Sub Flow.

## Explanation

There are two Flows created for this example: "Alphabet Flow" and "Number Flow", which will be used by the **Truth Table**. Both Flows use a **Show Pop-up** step to display a notification on the left side of the Studio. For this example, the **Main Flow** takes in a string value. The **Truth Table** evaluates if the input variable is '1' or 'a'. The **Truth Table** outputs the Flow ID of the "Alphabet Flow" or "Number Flow" based on the input. The **Run Flow** step is configured to "Runtime Selection" and a Default Flow is selected. The output of the Truth Table is mapped into the input of this step.

For testing, run the Main Flow and either a "1" or "a" for the input. The Pop-up will show which Flow was run.
