back and forth

Trying to get and object to move back and forth in etoys.  Something simple like:
forward 50
forward -50

It appears to do nothing.  When I go to the code level and add a wait:

forward 50
(Delay forSeconds: 1) wait
forward -50
(Delay forSeconds: 1) wait.


Still nothing.  Any ideas what I am doing terribly wrong?

Have you started the script ticking (clicked the little clock icon)?

You can try to do this:

    Player forward 50
    Player heading increaseBy: 180

or use a test tile and a boolean variable:

    movedForward
          true: Player forward -50
                  movedForward := false
          false: Player forward 50
                   movedForward := true
