Thanks guys. Really appreciate.

I basically wants the following: I have 4 scenarios (each one will be assigned a number, let´s say 1, 2, 3 and 4). I want to show these scenarios randomly to 'n' respondents (each respondent will be shown only one scenario, and we have n=100 for now). May I define something in php so I can get exactly the same number of responses per scenario. I mean I need to obtain out of the 100 times, 25 times the number 1 (representing scenario #1), 25 times the number 2 (representing scenario #2), 25 times the number 3 (representing scenario #3), and 25 times number 4 (representing scenario #4), while mantaining the random assigment of numbers? Your help will be highly appreciated. Thanks in advanced.
