Selector / Filter Programming - Expert coders only

We have created a video describing what this project is about. Here is the video, please watch this first: [login to view URL] Along with the written project scope here. ------------------------------------------------------------------------------------------------------- Welcome Page (or logo) appears then either a drop-down or multiple choice 1. Select instrument Violin Viola Cello Bass 2. Define silk-wrap design, 4 options we provide 1. Solid-single color (provided image is shown) 2. 2-color with thin wrap (provided image is shown) 3. Correli-Savarez variety (provided image is shown) 4. Warchal Variety (provided image is shown) This filters to: 3. Defining appropriate color(s) based upon the previously selected design. There's actually not anything for a user to do on step 3, but the system we develop should filter what it displays in steps 4 and 5 based upon what information the user has provided in steps 1 and 2. This filters to: 4. Selecting Peg End Design (3 options we provide) 1. Solid (provided image is shown) 2. 2-color (provided image is shown) 3. Corelli 2-color (provided image is shown) This filters to: 5. Selecting appropriate color(s) based upon previously selected design. My assumption is that the ability to filter all these options (and provide all the colors as you ask) would mean we'd have to have built a database of every conceivable wrap-style and color combinations from which the app can draw those conclusions. Viola! The exact string appears on the app!
