== Randomize answer options/sub questions  ==

In order to synchronize randomization of sub questions/answer options among several questions 

As a questionnaire creator 

I want to control the randomization with a random seed, which means that the system will generate a unique order based on one value of&nbsp;random seed 

=== Randomize answer options  ===

'''Example''' 

*I have a single question with drinks as answer options.

Use any random seed and a randomization range from 0 to 5 

'''Code''' 

*Add a Single question to Questionnaire editor 
*Go to menu Properties -&gt; Question scripts -&gt; Java script and input below script<br>

</source> 

''{{note}} quest.randomizeAnswerOptions(randomSeed, startIndex, endIndex): randomize answer options in a range specified by startIndex and endIndex, the order is unique for each randomSeed''
