Dear Prakash , 
When I use & ,I will still end up with a list like the following 
Pt Name  Date          Type of Encounter
--------------------------------------
pt y    12-Jul-11       Telephone
pt y    13-Jul-11       Telephone
pt y    14-Jul-11       Telephone
pt y    15-Jul-11       Telephone
pt y    16-Jul-11       Telephone
pt y    17-Jul-11       Telephone
pt y    19-Jul-11       Inpatient

The goal is to get two consecutive observations for each patient where the Type of encounter is Telephone and next observation id Inpatient.

Thank you,
Yours Sincerely,
Anwar
