Building Expresions for Sortable Data List Not Working

shared this problem ago

Solved

I am trying to create a data list that sorts and I have followed the instructions in the help. http://www.justinmind.com/support/sort-data-grid-columns/ Only that when building the expression it is not intuitive enough. I cannot replicate the image into my expression. I need to know exactly how it is done. I have version 6.8. Thank you.
