I think you intended that second "ArchitecturalModel" to be a variable (?ArchitecturalModel). As it is, it's a symbol, and it definitely doesn't match the facts in working memory.

Using the JessDE to edit your code would help in this case; the syntax coloring would let you more easily spot errors like this.
