I had a chance to look at this notebook. Unfortunately I can't run the code because I don't have the data files to run with it. I'll note that you will get a better experience if you break up the one large cell into several cells because the typesetting code can get a little creaky when it has to handle very large code blocks. If you want to do that, just put the insertion point at a reasonable point and type CTRL+SHIFT+D.
To make the code accessible, I suggest you replace the Import commands with CloudImport and give the full object URI for each of the data files. They will have to be made accessible to other users. If we get that working I can try to generate the Manipulate and see what happens.
