1. never use a construct like
x eq sysmis
because the outcome is always missing
Instead do this:
2. any new numeric variable is initialized to system missing so
compute error =$sysmis.
Handling missing values is tricky in transformations.

Subject: Syntax for Finding errors
I have been trying to write a little bit of syntax to identify errors in
my database. I know I am close but I can't seem to get the right syntax
for identify blank cells. In this case the error is defined as a case
with a value in the variable "region" but no value in the
variable "country". Region is coded 1-10 - and so is country. I wrote
the syntax below to identify all of these error cases as a value of 1 on a
new variable "error".
This is what I have so far....
Compute error = $sysmis.
If (region > 0) and (country = sysmis) error = 1.
...but it won't work!
