The example uses a field named preferred color - laptop bags to save the contact's answer.
Use the saved value
Insert the custom-field token into a later message. The example asks What is your color? and uses {{preferred color - laptop bags}} in the reply.

When the contact replies Green, the example message reads You chose Green color.

Check the contact record
Open the contact's details and look under Custom Fields. The example shows Green beside preferred color - laptop bags.
