If "screen" is selected as the value of an input field, where does the value come from when the guide runs?

When "screen" is selected as the value of an input field, this indicates that the input is expected to be provided by the guide user during the execution of the guide. The value does not come from a predetermined system setting or a formula but rather relies on the interaction of the user with the guide. In this case, the guide user is prompted to enter information, and their response populates the input field. This mechanism allows for dynamic interaction and personalization based on user contributions, making the user's input critical to the process.

The other options imply fixed or automated value sources that do not involve user interaction, which is not applicable in this scenario. The fundamental aspect of using "screen" signifies an expectation of direct user input, reinforcing the interactive nature of the guide.
