Dunno if this helps since the assignment was already due, but....
From Tools/Database Utilities/Switchboard manager where you created your switchborad pages (if you havene't, you would create new switchboard pages here), you select Edit for the relevant page, eg Main Switchboard.
Under Command you then select "Go to Switchboard" and under Switchboard you then select by name the other switchboard page which you should already have created (above).
