I am using IBM SPSS Version 21 and have run into a little problem using DESCRIPTIVES.  When I request the SUM stat, I get a 0 for SUM in a variable which I know has 1 case.  Here is the syntax I'm using:
DESC HYPERTENSIVE /STAT DEF SUM.
My variable is coded 0 or 1 for absence or presence.  The syntax works fine with other variables with the same coding, but with more than 1 case -- e.g., HYPOTENSIVE has an incidence of 110 and its SUM stat = 110.  The minimum is 0 and the maximum is 1, so I have no idea what's going on or how to fix it.

Here is the output I get...
Descriptive Statistics
                              N Minimum Maximum Sum Mean Std. Deviation
HYPERTENSIVE    244 0            1           0 .00   .064
HYPOTENSIVE    244 0            1       110 .45   .499
                               

Thanks,
