How do I fix a problem with array that is storing the same value in the other indexes?

This code should populate an array with random values that were loaded from a text file, without repetition. But instead of this, some values are appearing in more than one index. Could someone help me to find the problem in this code?

+ AJAX: On "questions" completed

-> System: Set totalQuestions to tokenat(AJAX.LastData,0,"|")

-> questionsArray: Set size to (totalQuestions+1, 1, 1)

-> questionsArrayTemp: Set size to (totalQuestions+1, 1, 1)

----+ System: controlRandom = 0

--------+ System: For "For Each Questions Set" from 0 to questionsArrayWidth

---------> questionsArray: Set value at i to tokenat(AJAX.LastData,i,"|")

---------> System: Add 1 to i

----+ System: Else

--------+ System: Repeat questionsArrayTemp.Width times

---------> questionsArrayTemp: Set value at LoopIndex to LoopIndex

--------+ System: Repeat questionsArray.Width times

---------> System: Set i to (floor(random(questionsArrayTemp.Width)))+1

---------> questionsArray: Set value at LoopIndex to tokenat(AJAX.LastData,i,"|")

---------> questionsArrayTemp: Delete index i from X axis

It's hard to make sense of your code without seeing the project file and the structure of txt file with questions.

If you need a randomized array, you can initially set array width to 0. Then read a new question from AJAX and insert it at index int(random(array.width+1))

Or you can load all questions into the array at Y=1, put random values into Y=0 and then use "array sort".

Or load all questions into temp array, then pick a random element, push it into another array and remove from the temp array. Repeat until all questions are transferred.

Hi dop2000

Thanks for the suggestions.

I decided to use this solution:

+ AJAX: On "questions" completed

-> System: Set totalQuestions to tokenat(AJAX.LastData,0,"|")

-> questionsArray: Set size to (totalQuestions+1, 1, 1)

-> questionsArrayTemp: Set size to (totalQuestions+1, 1, 1)

----+ System: controlRandom = 0

--------+ System: For "For Each Questions Set" from 0 to questionsArray.Width

---------> questionsArray: Set value at i to tokenat(AJAX.LastData,i,"|")

---------> System: Add 1 to i

----+ System: Else

--------+ System: For "For Each Questions Set" from 0 to questionsArrayTemp.Width

---------> questionsArrayTemp: Set value at i to tokenat(AJAX.LastData,i,"|")

---------> System: Add 1 to i

--------+ System: Repeat questionsArray.Width times

---------> System: Set iTemp to int(random(1, questionsArrayTemp.Width))

---------> questionsArray: Set value at LoopIndex+1 to questionsArrayTemp.At(iTemp)

---------> questionsArrayTemp: Delete index iTemp from X axis

And it worked very well. I just don't understand why the other solution generated so weird results. But this is not a problem.
