On Vocaloid wiki, I am trying to create a template that has multiple parameters. I completed the parameters, but the issues is trying to get a sub-template to function correctly.
 * It is called Derivatives(x4) and it is based on this template called Derivatives, so they have the same parameters only (x4) has more of them.
 * The Derivatives template transcludes a sub-template called Thumbnail. This allows (for example) YouTube video thumbnails to show up when a video URL is placed in a parameter. The sub-template also includes generic icons for sites that we didn't figure out the thumbnail coding for.
 * I attempted to simply add (x4)'s parameters to the existing sub-template but found it didn't take, so instead of messing with it more (because it is widely used) I created Thumbnail (x4) to test things out and attempt to make it work on there before I did anything with the original. Only it seems I can get one thumbnail to appear. Results here.
 * I am wondering if I should bother doing that and instead just try to place the 'thumbnail' content into the template itself because originally the Derivatives thumbnail content was that way before it was moved (to a sub-template) for easier editing. As seen here 03:29, January 8, 2014.
