Hi - if you want to sort by a column that is not shown, try these steps...
- Create the column you want and switch to text mode
- Find the querysort line and copy it
- Go to another column that you do want to display and switch to text mode
- Find the querysort line and paste the info to replace it
- Add underneath it
sortOrder=1
sortType=asc
And then you can just delete the other column. :)
