Hi,
if you remove the "S0==1" part the quota works.
So it is not because of the hidden question.
Because I do not know why there is this hidden question and the assignment to it, I only used the equation to create the quota.
S1fc:
{if(S0!=1,0,if(S1==1,1,if(S1==2,2,if(S1=

,3,if(S1==4,4,if(S1==5,5,6))))))}
(This you may adapt to all your needs)
and the quota:
S1fc==1
