Okay I give up . . . Making Blocked Units

[wrw1]

Okay. I think I have tried everthing ....

I have a door with two side lites panels/windows. I use the shift button to select all three objects and then go to the "edit" button to try to select the "make block" botton but it does not appear to be there (or anywhere else). I will also have a transom but understand that the blocking needs to happen seperately with the horizontal and vertical, but again I don't see any make block button.

Any thoughts or suggestions would be appreciated.
