Hello,  
I have tried editing an activity that contains copy previous. I looked at all the suggestions that Desmos provided in the warning message, but still can’t seem to get it to work. Can some one help? Here is the activity that I am trying to edit.  
[[Copy of] Multiplying Fractions](https://teacher.desmos.com/activitybuilder/custom/665f479505d45526dc3e6ba5)

Can you clarify what you are asking, you are unable to edit the activity linked?

I think [this solution](https://teacher.desmos.com/activitybuilder/custom/666d0527c442b8a8ac3be69f#preview/c404a7e0-ef4e-46f9-8bf0-9eb1e1a5575e) might be what you’re looking for. I assume you meant Screens 6 and 8.  
I changed Screen 6 by copying the actual graph from Screen 4 (it was easier than the full screen graph) into it. Then imported the values, n, d, n\_1 and d\_1 that students adjust from Screen 5, and removed the background sink.

You’ll see a warning because students could potentially delete the variables from the full-screen graph. To mitigate that, you may want to consider making sliders in the graph, or draggable points that adjust the box divisions and hiding the actual variables.
