<div dir="ltr">Hi Emily,<div>Here's my opinion:</div><div>I would not have the student start over. Just delete "All references" and select "OK" at the part where the Dummy is, from the Object Tree, and have your student do only that part again. You will notice the "empty" places/null set where you can just select the new items from, so that the only code that is eliminated, is the code with the error, or the item that you can no longer see; then you will replace it with the objects that you can see.</div><div><br></div><div>Hope that helps. Good-luck!</div><div><br></div><div>Take care,</div><div>Susan</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 31, 2016 at 12:44 PM, EMILY REED via alice-teachers <span dir="ltr"><<a href="mailto:alice-teachers@lists.andrew.cmu.edu" target="_blank">alice-teachers@lists.andrew.cmu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
