How do you add quotas? For instance you may wish to only have 100 male and 100 female respondents, and once the quota is reached (e.g. male) then a message is displayed to future male respondents indicating the survey is now closed if they attempt to start. Secondly, how do specify the maximum allowed completed interviews in cases where you are not using quotas. For example, maximum 300 interviews, and then it displays a 'closed' message once that maximum is reached.
