Hi Marla,
There is another way of doing this! The set configuratin block (scroll down in the "Variable" category) will allow you change the movement timing. You can also use it to change the timing of transition effects (fade in, fade out). Enter the value in milliseconds, for example, 2500ms = 2.5 seconds. If you want to do something after it finishes moving, add a 2.5s wait block after the move, and then the other action that you want.
I usually set the dropdown to "current event" so that it only applies to this particular action, but you can also leave it on "lesson" and it will apply to all the move blocks in the lesson.
See attached image. Hope that helps!
