You've created a query that picks up the source file from a cell in an Excel worksheet. This is to allow users to easily change the file that they want the query to address. You post the file with the query to a network location so others can use it. The queries run fine for you but whenever anyone else tries to refresh the query they get an error that states "Formula.Firewall Error: this query references other queries or steps, so it may not directly access a data source.
