Hi,
okay, the problem is simplified:
Display all groups which where "used", but not more than three.
Solution:
1. Enter the same name in "randomization group"
2. Enter in "relevance equation" of: (SVCUSE_SQ001=="A1") and (G1Q1.gseq lt 4)
with "SVCUSE_SQ001" the first subquestion of your "selection question", and
"G1Q1" the first question in group G1 (Service 1)
...
(SVCUSE_SQ002=="A1") and (G2Q1.gseq lt 4)

Better, you send a sample as *.lss.
