So that I understand correctly, you ask a single response question ...

Are you ...
1 Male
2 Female
3 Diver

And the quota question then needs to be allocated as follows ...
If Male, quota=1
If Female, quota=2
If Diver=quota is randomly allocated to a 1 or 2

Is that correct?

If so, you can create a gender quota variable and save the answer in there, and then operate the quota off the gender quota variable.

Here's the steps ...

1/ Go to the pass-in fields and create a variable called \"QTGender\" and set it to a whole number.

2/ Insert this Perl Script in to the footer of a question that is not skipped and appears after the gender question (which I assume is Q1).


Begin Unverified Perl

 if(VALUE(\"Q1\")==1)
  {  
   SETVALUE(\"QTGender\",1);
  }  
 elsif(VALUE(\"Q1\")==2)
  {  
   SETVALUE(\"QTGender\",2);
  }  
 elsif(VALUE(\"Q1\")==3)
  {  
   SETVALUE(\"QTGender\",SYSRAND(1,2));
  }  

End Unverified

Note #1:I have assumed your gender question is Q1. Change all Q1's in your Perl Script to whatever your question number should be.
Note #2:I have assumed your gender quota variable is QTGender. Change all QTGender's in your Perl Script to whatever you prefer.

3/ Create your quota question with 2 cells ...
1=Male, set the logic to QTGender=1
2=Female, set the logic to QTGender=2

If I have assumed incorrectly about the gender being asked, and it is a pass-in variable instead, the above approach will still work nicely.
