AutoCAD Architecture :: Moving Doors Within Wall?

have trouble moving doors or windows within a wall?

I am trying to move a door so that the door is flush with a face of wall. The prompts in acad do not match the instructions. 

For instance;  select door, okay.  then from anchor panel select 'reposition within wall', okay a red line appears and prompt to 'select position on the opening'.  okay so i click the face or side of door jamb then select a reference point.  (guide says select point to measure to) and on and on.  Door never moves.

it should be; select door, select reposition in wall, select reference point (interior, exterior, midpoint), select the desired location.  Done. 

Instead it is select this that and the other , measure from here, select, click.click click.
