No problem - happy to help.

With the notes already entered, click and hold on one of the notes and drag it to a new place on the stave. You should hear the sound change as it passes over each line and space. On the header strip there's a box which displays which note and octave you're on. Now drag the note way below the bass clef until the box reads G2 - this should be the stick click.

I have to say, though, the long whistle sounds like fun.
