Why can't I use an alisa ParentName:[LastName]&","&[FirstName] for the ParentT (get rid of the FirstName, LastName of ParentT's Column)?  I tried but I'm getting a message "The specified '[FirstName]' could refere to more than one table listed in the FROM clause of your SQL statement; even though I selected StudentT in the Table.  All I am trying to do is Concatenate the fields together as one. This on 03:54 on the video timer.  My database built a bit different using City, State, ZipCode as a separate field.  But it works!
