Roof/Wall Question

[Acesalad]

I was doing the Basic Roof training webinar and in the part where he designs the Shed style dormer, I followed the instructors directions but I still get a gap in the walls.  Attached is a picture of my screen.  Does anyone know how to eliminate these gaps?

Select the wall, in plan or camera view and drag it to fill the gap.

Thank you solver.  This seemed to work although I got the "This operation modifies one or more automatically generated walls. The walls(s) will be retained and will not regenerate automatically. Would you like to continue with the operation?" message.  I did not think to go up to the Attic level and stretch the walls.  I also took your advice on my signature.  Thanks again!
