Which method allows you to add values from a screen component to a collection variable?

The method that allows you to add values from a screen component to a collection variable is through the use of an Assignment element. The Assignment element is specifically designed to manipulate variable values within a flow. When you need to gather user inputs from a screen component—such as text input, radio buttons, or checkboxes—you can take the value provided by the user and assign it to a collection variable within the flow.

By using the Assignment element, you can effectively gather and store multiple values into a collection, which can then be processed or used later in the flow. This functionality is critical in scenarios where you want to accumulate inputs from users in a session and utilize them for further processing, such as summarizing information, creating records, or making conditional decisions based on the input.

Other methods such as using a Decision element, Loop variable, or Record Variable do not serve the purpose of directly adding user inputs to a collection variable in the context of screen components. The Decision element helps determine a path based on certain criteria, the Loop variable is used to iterate over a collection, and the Record Variable is specifically for handling records rather than user input from screen components.
