There are 5 different options you can answer lets call them:

A (1)
B (2)
C (3)
D (4)
E (5)
F ( no opinion, was also possible to answer, but i cant find it in the datafile)

when i run descriptive statistics this happend:



does it mean no one answered A? and what does the 0 mean. is a 0 a missing value also?

Where did you get your data? At first glance, it seems your value labels are not correct. Perhaps "A" was coded as "0", "1" = "B" and so on? Is that even possible? As a first test, show output as values instead of value labels (http://www.spss-tutorials.com/names-and ... in-output/) by running this:

set tnumbers values.

frequencies [variable name(s)].

This will give you the frequencies per value rather than per value label and will tell you which values are present in your data. Note that some values present in your data may not have a value label. Reversely, some value labels may not be present in your data.

First make sure your value labels are correct. Then specify missing values.
