+Here's an example of using a function to create a custom display that can be used to provide a range of standard data-driven interfaces. In this case, the function generates a display offering the user a set of different buildings to construct:

+And to use this function, another part of the script calls it with a data table set up to fill in the names, items and building types involved :
