To import a sound, on the left hand side you have the Project Workspace (or PWS). You should have sections marked for Images, Sounds, Materials etc. Right click the Sounds section, and then click Import Sound. Then find your sound in the WAV format.

You should just be able to drag the sound from the Sounds folder to the Action or Choreography.
