Subject: conditional compute syntax incorrect

I am now calculating the score of a 9 item depression questionnaire
(PHQ-9). I have dichotomized the 9 questions into the variables
PHQ_tiredS, PHQ_sleepS,  PHQ_eatS, PHQ_concS, PHQ_badS,  PHQ_movemtS,
PHQ_anhedS,  PHQ_downS, and PHQ_deathS (0=no and 1=yes). The criteria
for the new variable ( MajDeprsn) to be positive (yes=1) is two part.
First either PHQ_anhedS or  PHQ_downS must be positive (=1) and then the
sum of all 9 variables must be 5 or greater. Results from this code are
all 482 cases=0. I think my parenthesis are wrong.  Thanks, Jan


Compute MajDeprsn=0.
If (PHQ_anhedS=1 or PHQ_downS=1) and sum(PHQ_tiredS PHQ_sleepS
PHQ_eatS PHQ_concS PHQ_badS
  PHQ_movemtS PHQ_anhedS PHQ_downS PHQ_deathS) ge5  MajDeprsn=1.
FREQUENCIES  MajDeprsn.
