Remember to use the Next column and 
Previous column option buttons on the 
Modify Columns form, to move between columns. 
 
        Keeping Sorting as 
0-9 for HBORE, switch Sorting to 0-9 for TBORE. Note that the 
Precedence button is now set to 2, and that the precedence is also shown by 
Sort 1 and 
Sort 2 against the columns on the 
Modify Report Template form. Go back to the HBORE column, and note that the Precedence is shown as 1. This means that the Branches will be sorted first in order of Head Bore, and second in order of Tail Bore.
