How can I use a user's response in a subsequent message?

You can do this by using the toolbar inside the message text field.

Follow these simple steps: 

1. In the dashboard, go to the message where you would like to use a user’s response.
2. Place your cursor where you’d like the response to appear in the message. A toolbar will appear in the bottom-right hand corner of the message text field. 
3. Click on the ‘Response’ button.
4. Choose the response you would like to appear from the drop-down list.  
5. Click ‘Insert’.

Done! The response provided by the user will now appear in the message in the chat interface. 

Note: if you can’t find the message you’re looking for in the drop-down list, please remember that the message containing the response you’re using must be connected to the message you wish to insert the response into.
