Select Ascending or Descending.

Ascending Select Ascending if you want the sort orders to be in ascending order. For example, if you want the clients to print in alphabetical order from A to Z, you would select Ascending.
Descending Select Descending if you want the order to be in descending order. For example, if you want the clients to be printed in order based on Balance Due with the clients having the largest balance due printing first, then you would select Descending.

Note: You cannot mix ascending and descending orders when using both a primary and secondary sort. Both sort orders will be either ascending or descending.
