Survey is with four test groups (showing different concepts after screening questions) and same quota for each test group;
Also I like to conduct the interviews of the four test groups randomly.
So I create a variable TG (test group) with SYSRAND
[% Begin Unverified Perl
my $rand = SYSRAND(1, 4);
if($rand == 1)
and make quota questions with quota of the four test groups f.ex. for age.
If I set a value for TG, f.ex. "P" and quota is full, I loose this respondents. But maybe this quota is not closed in TG "Q".
How could I fix a randomly variable for the test group and could change the "TG" if quota is full in this test group.
Thanks a lot!
