I am trying to get a total percentage availability of a group of nodes. Right now I am listing them individually. I am doing this by using the Availability of Each Node Content option. I then applied a Custom Property to the nodes I want to show and use the Filter Nodes (SQL) option to only show the nodes I want to show. At the bottom of this list thought I would like to sum them up and give a percentage of total availability. I have tried adding them to a group and using the group availability option but it always comes back as 100% and does not work correctly.
