I can't for the life of me figure out how to copy paste information into the practice environment. I can copy and paste entire cells but not information INTO a cell. For example, when attempting to use an operation on a data set, the above data set in a seperate cell doesn't always apply to the operation cell (error: variable is undefined) my solution so far has been to copy the cell with the variable information above and then merge the cells. But it feels also though you should be able to simply copy paste information into the cell... Anyone have a solution for me.
