Update Query (with Nested Sql) Not Working

hi guys,
i have this sql that filters 2 tables to give me the highest number against a record and then i want to update the 1st table. but it dosnt seam to work it brings back the correct data but the sql has generated a non-updatable query.

any ideas?

UPDATE [SELECT ARCtblErrorInfo.Uber, Max(ARCtblHistory.Status) AS MaxOfStatus
FROM ARCtblErrorInfo LEFT JOIN ARCtblHistory ON ARCtblErrorInfo.Uber = ARCtblHistory.Uber
WHERE (((ARCtblErrorInfo.Status)=121))
GROUP BY ARCtblErrorInfo.Uber]. AS test INNER JOIN ARCtblErrorInfo ON test.Uber = ARCtblErrorInfo.Uber SET ARCtblErrorInfo.Status = [test].[MaxOfStatus];
