sql statement structure






when I run the following, there are no problems...

SELECT qfGrp, qfDate, clSupr, qfUser, qfStCd, qfArea, qfBank


FROM BANKCHDR
Join BANKCDTL On qFStCd=qEStCd And qFArea=qEArea And qFBank=qEBank
And qFGrp=qEGrp And qFTYPE=qETYPE And QFCRCD=QECRCD Join CSRCLVLPF
On QFGRP=CLLGRP AND QFUSER=CLCSR WHERE QFTYPE = '3' AND
idate(QFDATE) >= (CURRENT DATE - 7 DAYS) AND CLSUPR IN ('MELANIEG',
'MARYB', 'AMYR', 'MELISSAJ', 'SERGIOC') AND QECSEQ = 1 ORDER BY
QfGRP, QFDATE, CLSUPR, QFUSER

But when I try to add... Max(Case When qeCSeq=1 Then
substring(qecmnt,10,8)
Else '' End) As
TimeIn

as in the following, I get... "Column QFGRP or expression in SELECT list
not
valid. "...

SELECT qfGrp, qfDate, clSupr, qfUser, qfStCd, qfArea, qfBank,
Max(Case When qeCSeq=1 Then substring(qecmnt,10,8) Else '' End) As
TimeIn

FROM BANKCHDR
Join BANKCDTL On qFStCd=qEStCd And qFArea=qEArea And qFBank=qEBank
And qFGrp=qEGrp And qFTYPE=qETYPE And QFCRCD=QECRCD Join CSRCLVLPF
On QFGRP=CLLGRP AND QFUSER=CLCSR WHERE QFTYPE = '3' AND
idate(QFDATE) >= (CURRENT DATE - 7 DAYS) AND CLSUPR IN ('MELANIEG',
'MARYB', 'AMYR', 'MELISSAJ', 'SERGIOC') AND QECSEQ = 1 ORDER BY
QfGRP, QFDATE, CLSUPR, QFUSER


anyone know what I am missing here???
