Introduction When building solutions in Copilot Studio, you may use Adaptive Cards to collect multi-choice input from users. The selected values from a multi-select field are stored as a table variable. However, if you want to pass these values to an Agent Flow (for example, to create a SharePoint list item), you need to convert the table variable into a single string. This post shows how to concatenate the selected values from a multi-choice Adaptive Card field into a semicolon-separated string using the concat function in a Set Variable value action within your topic.
