Maximum Value

SQL 2008

I have a table with some example data as follows

Task   Audit    Status
1        22        Draft
1        23        Pending
1        24        Complete
2        25        Draft
2       26        Pending

I simple want to bring out the maximum audit value for each tasks

Results would be

Task Status
1       Complete
2       Pending

Any help would be appreciated

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Should be simple as:
WITH TASK_CTE (Task, Audit)
AS
(SELECT Task, MAX(Audit)
FROM TableName
GROUP BY Task)
SELECT T.Task, T.Status
FROM Task T
INNER JOIN Task_CTE T2 ON T.Task = T2.Task AND T.Audit = T2.Audit
