How to include other columns in nested Select statement with

Question

I have a select statement and in that i have a nested select statement , and in nested select statement i have aggregate function on one column , I want to add more columns with this nested select statement , and i just want to group by on one column ,

check the below query

SELECT t1.DynamicIndicatorID,t1.District,t1.Quarter,t1.District,t1.TFA,t1.TFB,t1.TFG,t1.TFW,t1.TFM,x.fileID as fileID,x.filenameName as FileName

FROM DynamicIndicatorsTargetsForPu t1

LEFT JOIN (

SELECT IndicatorID,filenameName, MAX(fileID) AS fileid

FROM tblUploadedFiledetailsForPartners group by IndicatorID

) x ON t1.DynamicIndicatorID = x.IndicatorID where t1.UserId=59

I am getting an error

Msg 8120, Level 16, State 1, Line 4

Column 'tblUploadedFiledetailsForPartners.filenameName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

I want to add more columns in Nested select statement as i have to show these columns as well but i want to group by on just one column .
