Okay, I am totally new to this and I can not figure out how to enable the Computational Layer so that I can copy and edit some of the activities in desmos.   Every time I go to “Copy and edit” it gives me the message below so click on learn more and I just get a really long document.  I feel stupid so I hope someone can help me.  What am I missing?
To edit this activity, you need to enable Computation Layer. Learn More
             
            
              
              
              
            
            
           
          
            
            
              Mxesptein,
Thank you so much for your response because it helped me to I figured out where I went wrong.  I had previously gone into Desmos labs and clicked on CL. However, I had not done that while in the actual activity screen that I wanted to enable the CL.  I am not ready to work in CL yet.  I just wanted to delete slides and make a shorter activity so this worked perfectly.
