All I did was place the whole file into the entitybank in its own folder called glass Floor
As you can see from my screenshot I have this working
You could try deleting the dbo file and the bin file within the Glass Floor Folder or you could look at the code that I have placed below to check see if everything is the same
It could be the fact that there is a file that is not in the right place.
