Hello all.
I have a small constraint in my chk file and I wonder how I could program
it.
I have 8 options (8 variables V1 - V8). Interviewers are asked to chose
their top 3 options. So that the legal values are 1, 2, 3 and there must
not be the same value twice. I dont know how to write short instructions to
check that.
Thanks for your advices.

Serge.
