SubQuery Returns More Than One Row - Update Query

Hello,

I'm trying to update column based upon the results of a subquery. I'm getting the error that my Subquery returns more than one result. I've tried adding the EXISTS or IN keywords and cannot get the syntax right. I can't find any examples of how to write this with an Update query.

Here's my query:

UPDATE temp_UpdateRemainingHours
SET UsedHours =

(SELECT dbo.vw_SumEnteredHours_byCHARGE_CD.SumEnteredHours, dbo.vw_SumEnteredHours_byCHARGE_CD.CHARGE_CD
FROM dbo.vw_SumEnteredHours_byCHARGE_CD INNER JOIN
dbo.temp_UpdateRemainingHours ON
dbo.vw_SumEnteredHours_byCHARGE_CD.CHARGE_CD = dbo.temp_UpdateRemainingHours.CHARGE_CD)

FROM dbo.vw_SumEnteredHours_byCHARGE_CD, temp_UpdateRemainingHours

WHERE
dbo.vw_SumEnteredHours_byCHARGE_CD.CHARGE_CD = dbo.temp_UpdateRemainingHours.CHARGE_CD


;
