Always place the basepoint parameter at the 0,0 point within the block. Previously you had the 0,0 point at the corner so I put the basepoint parameter there. Now you moved it to the center, so the basepoint parameter should go there. The center makes more sense to me. The chained point move for the basepoint is good practice to eliminate the 'basepoint bug'. There is more info on that in other threads.
You need to pay attention to which linear parameter endpoint you select to associate with a given action. You had the vertical move action associated with the startpoint of the vertical linear parameter. That endpoint doesn't even have a grip so the move action would never be activated, ever.
You also need to understand the rules of stretch windows and selection sets. You need the stretch window to surround the vertices you want stretched and not to surround the vertices you do not want stretched. If an object is in the selection set of a stretch action and either all or none of its vertices are surrounded by the stretch window, then it will be moved rather than stretched.
I never used any angle offsets in the screencast I previously posted so I'm not sure why you used the 180° angle offset in the one action, if you were trying to follow the screencast.
The screencast shows every single action taken. Pause often and pay attention to the command line as well. Report back if you get stuck or need further explanation.
