Having a problem with a subre****t

Hello,

I am having an issue with a subre****t that only works part of the
time.

I have a re****t that shows all personnel assigned a BSC and a sub
re****t that shows all personnel not assigned a BSC.

BSC's are broken down into UIC's.  The main re****t's query asks for
the UIC as criteria and filters the data to display only that UIC's
BSC's.  The subre****t is linked to the main re****t via the UIC.  now
when I enter a UIC of 46965, the subre****t works, but when I enter in
any other UIC (there are three different UICs all together) the
subre****t dosn't populate.

When I run the query for the subre****t, it shows all three UIC's but
the subre****t wont populate when included into the main re****t.  Out
side the main re****t the subre****t works fine,

Any help would be greatly appreciated.

Sincerely,
Michael Martin
