I'll try to explain this as clearly as possible...

I need to compute how long clients were in a program. Originally the data was done so that clients had multiple cases. Thanks to the list it has been restructured so each client has one row.

Everytime a client came in they had their tracking data recorded (11/28/2003), and a round (Round1, Round2, etc) denoted.

So in the new restructured database it goes.

ID   Tracking1   Rd1    Tracking 2 Rd 2 ......
213  11/28/03    1        12/28/03    2

I need to subtract the clients last tracking date from their first tracking data.  The issue is they all had different numbers of tracking dates....some with 2, one with 44, and all in between.

Any suggestions? either syntax or a logic computation.

Greatly Appreciate Any Help
