need help in making levels work in the campaign

ok i got all the imported data in, all the custom data in and have a map loaded up into the campaign editor but it says the map is not going to be used and its highlighted in blue

whats going on and how do i fix it?

Go to the Loading Screen Tab of the Campaign Editor and clic on Add button in the Edit Menu.
There you can choose your map as first button.

Thank you very much
