What am I missing (aside from sufficient experience)?
The "Frequency Coordination" tab operates independently from the "Inventory" tab. The Analyze and Calculate operations only deal with what's been loaded into the Frequency Coordination workspace, and it looks like you haven't loaded anything in yet.
Hit the "Select Frequencies From Inventory..." button, then use the "All frequencies from inventory" option. This will make everything in your inventory show up in the coordination workspace. Then you can run the analyze and calculate functions on your channels.
Once you've created you coordination and are happy with what you're seeing, hit the "Assign and Deploy" button to send the frequencies you've calculated back to the "Inventory" tab. If your ULXD receivers are talking with Wireless Workbench, "Assign and Deploy" will also reprogram the receivers (you'll need to resync the transmitters).
