Mitzie, what they mean is that you create a basic prim, or even a complicated prim set with buttons. The design is entirely up to you. Once you have created your prim set, you drag the script and the notecard into it. Once that is done, you can use the prim set you created as your applier either as a HUD attachment or as something razzed on the ground. With button prime and the correct setup, you could set it ways of switching to different textures. I haven't done this yet, just researching it now for a project I'm working on. Hope this helps
