ILS Assistance with EFIS

I was told to get assistance at ILS approaches you can go to Aircraft - Navigation- EFIS, as to where you can choose a landing aid, Ie balloons, yellow brick road, telegraph poles ect ect.
However when I go to this aid, it will not let me put a dot in the ILS loc ect ect, its all greyed out.
What am I doing wrong ?
