Once you've got your Shockwave or Flash movie finished, open the page where it will go and place the cursor in the correct location. Call up the Object Palette and make sure you're in the Common menu using the pulldown list at the top. Click on either the Shockwave button (which looks like the Shockwave log) or the Flash button (like the Flash logo). When the dialog box comes up, use it to open the correct movie file. Use the Property window to set the height, width, and any other necessary properties.
