I am trying to have a random set of questions.
i tried having a variable with a random value of 1-5.
and conditional branch of which the value of the variable is selected then the question is the same number.
E.G Control Variable[001: RandomNum] = Random No. (1...5)
Conditional Branch: Variable [001: RandomNum] == 1
Text: Question number 1
Conditional Branch: Variable [001: RandomNum] == 2
Text: Question number 2
and so on....
but my problem is, random number is sometimes duplicating like 1-2-2-3-2. so the questions are being repeated. i need it not being repeated.
hoping for your help guys. Thanks !

Well, one way would be to use self-switches inside a loop, like this:
Loop
Control Variable[001:RandomNum] = Random No. (1..5)
Conditional Branch: Variable [001: RandomNum] == 1
Conditional Branch: Self-Switch A is OFF
Question Number 1
Control Self-Switch: A = ON
Break Loop
Branch End
Branch End
Conditional Branch: Variable [001: RandomNum] == 2
Conditional Branch: Self-Switch B is OFF
Question Number 2
Control Self-Switch: B = ON
Break Loop
Branch End
Branch End
...
Repeat Above
It's a bit of a pain and you could only have four though (unless you use game_guy's More Self Switches (http://rmrk.net/index.php/topic,42808.0.html) script). You'd also need a way to break the loop immediately if no more questions were left.
You could also do the same, except using a variable instead of self-switches to track which questions have been answered. For the first question, you'd add 1 to the tracking variable. For the second question, you'd add 2; for the third question you'd add 4; for the fourth question you'd add 8; for the nth question you'd add 2^n-1, etc... Then you could know whether each question has been asked before by looking at that tracking variable.
However, I don't really see the point of randomizing the questions if you need to have them all asked anyway? It's a lot of work for a feature of questionable value.
Also, there might be an easier way to do it, but that's the first that came to my mind. I have a sunburn though, so I'm not really thinking clearly.

Thanks for your reply.. this would be a great help. i think i'll just substittue the self-switch with a variable. ;D

I suggest you do it this way. It's simply way too dangerous. First of all who knows how many rounds it can take, secondly and most importantly the loop becomes an infinite loop the 6th time it's called. You can clean it up and protect it, but having some code which will freeze the game if you miss a route into the loop a 6th time is not nice at all.
Luckily only some slight alteration are needed to make the loop safer.
Control Variable[001:RandomNum] = Random No. (1..5)
Loop
Conditional Branch: Variable [001: RandomNum] <= 1
Conditional Branch: Self-Switch A is OFF
Question Number 1
Control Self-Switch: A = ON
Break Loop
Branch End
Branch End
Conditional Branch: Variable [001: RandomNum] <= 2
Conditional Branch: Self-Switch B is OFF
Question Number 2
Control Self-Switch: B = ON
Break Loop
Branch End
Branch End
...
Conditional Branch: Variable [001: RandomNum] <= 5
Conditional Branch: Self-Switch B is OFF
Question Number 5
Control Self-Switch: B = ON
Break Loop
Branch End
Branch End
Control Variable[001:RandomNum] -= 1
Conditional Branch: Variable [001: RandomNum] <= 0
Break Loop
Branch End
Repeat Above
Personally I would use an extra variable to keep track of the number of questions left so I wouldn't need to use a loop at all, but practically I doubt there are any significant difference with only 5 questions.
*hugs*

here is what i did:
Loop
Control Variables: [0010: RandomQues] = Random No. (1...20) --->>> for 20 sets of questions
Conditional Branch: Variable [0010: RandomQues] == 1
Conditional Branch: Variable [0026: q1] == 0
Text: QUESTION
Control Variables: [0011: NuumberofQuestion] += 1
Control Variables: [0026: q1] += 1
Else
Conditional Branch: Variable [0011: NumberofQuestion] == 5
Break Loop
Branch End
Branch End
Branch End
Conditional Branch: Variable [0010: RandomQues] == 2
..... and so on....
Conditional Branch: Variable [0011: NumberofQuestion] == 5
Break Loop
Branch End
Repeat Above
it works fine,
so thanks to everybody! ;D
