Hi guys, I am presently trying to design a certain type of question but I am having lots of trouble

. The version I am working with is 2.00+Build 130305.
So first, I would like to have an 'array by column' question where I can
'check' multiple choice answers (the one I've just created with 'array by column' is perfect but does'nt give me the posibility to 'check' more than one answer per Y column).
Second, I would like that if the answer to the previous question is 'yes', than a new question pops out directly after checking
'yes' to
each previous statement.
Third, I have certain questions that need to be ask 'TO ALL' people answering the questionnaire whatever the previous answers are. I have lots of scenarios so it is difficult to set conditions for all the scenarios. And if I don't set conditions at all, the question does'nt pop out where it should be but instead is in the questionnaire since the very beggining.
Thanks a lot
