Have installed the demo version onto Win 2003 server with MOSS 2007. All the demo gauges work fine.
I've installed / registered the web parts into a separate web app on the server (port 80).
I can add the gauge web parts OK to a web part page. In the gauge designer when I enter values into the data souce for a database connection it always gives an error "Error: Cannot connect to data source. Error was:ConnectionString cannot be an empty string." regardless of the type of DB Connection.
Additionally if I try to change the data souce to list or web part table, the parameters required don't change and always stays on database parameters.
some screen shots attach
I suspect I'm doing something wrong, or maybe a permissions problem or something ? Any pointers on where to look ?
