To add a variable's stored value to a collection variable, which element should be used?

The most appropriate way to add a variable's stored value to a collection variable is by using an Assignment element. This element allows you to perform operations on variables, including adding values to collection variables which can contain multiple values.

When you use the Assignment element, you can specify that you want to add the content of a single variable (the value you want to include) to a collection variable (such as a collection of records or other data types). This manipulation occurs within a flow, enabling you to gather multiple entries into a single collection for further processing or output.

The other elements listed serve different purposes:

• The Loop element is designed for iterating over a collection, not adding to it.
• The Get Records element is used to retrieve records from the database, rather than modifying or adding values to a collection.
• The Input Screen element is focused on capturing user input during a flow and doesn’t manipulate data directly in terms of adding it to a collection.

Using the Assignment element is essential for correctly updating your data structures within Salesforce flows, which allows for efficient data handling and manipulation during automation processes.
