Calculate by Field

Hello,

I am trying to write a query that will show me the number of patients I have on each team.  Here is the query I pulled out of the query builder in sql, but I can not figure out how to get it to sort by team and calculate the number of patients per team.  Any help would be greatly appreciated.

SELECT     TOP (100) PERCENT dbo.VW_PT_BRANCH.TEAM_DESCRIPTION AS Expr1
FROM         dbo.O_DATASET INNER JOIN
                      dbo.PT_BASIC ON dbo.O_DATASET.DATASET_ID = dbo.PT_BASIC.DATASET_ID INNER JOIN
                      dbo.PT_ADMISSION ON dbo.PT_BASIC.PATIENT_ID = dbo.PT_ADMISSION.PATIENT_ID INNER JOIN
                      dbo.VW_PT_BRANCH ON dbo.PT_BASIC.PATIENT_CODE = dbo.VW_PT_BRANCH.PATIENT_CODE
GROUP BY dbo.PT_ADMISSION.ADMIT_DATE, dbo.PT_ADMISSION.TERMINATION_DATE, dbo.O_DATASET.DATASET_NAME,
                      dbo.VW_PT_BRANCH.TEAM_DESCRIPTION
HAVING      (dbo.O_DATASET.DATASET_NAME = 'Hospice Care Team Inc') AND (NOT (dbo.PT_ADMISSION.ADMIT_DATE IS NULL)) AND
                      (dbo.PT_ADMISSION.TERMINATION_DATE IS NULL)
