Generate random code for MTurk users

Question

HI,

I would like to publish my survey on MTurk and therefore, I need an individual code generated at the end of my survey.
I read through this question https://support.soscisurvey.de/?qa=38/how-can-generate-mturk-completion-code-at-the-end-of-my-survey and I considered the other help pages for placeholders, random generators and value().
So far, I created a random generator variable (E202) and a text element (E203) and one page between the last "normal" and the official end page. On this page, I included my code:

question('E202');  // Random generator variable
// To stop when no codes are available anymore
if (value('E202_CP') > 0) {
  text('quotafull');
  buttonHide();
  pageStop();
}
// Defining the code variable and saving codes in it
$code = value('E202'); 
// Prepare a placeholder 
replace('%code%', 'E202', 'response');
// this placeholder is used in the text element below
question('E203');  // MTurk Code

When I now click through the survey, it just skips the new page.
If I put the code on the last "normal" page, it displays the text element (E203), but does not include a code from the generator. Same problem if I put the first rows of the code on the first page and only E203 on the last (not end) page...

Can you please tell me where the error is?

THANK YOU!

The chapter on this has not yet been translated, but you may give Google Translate a try: https://www.soscisurvey.de/help/doku.php/de:create:vouchers

> If I put the code on the last "normal" page, it displays the text element (E203), but does not include a code from the generator.

Could you please add the debug information from this page to you question? Thanks. https://www.soscisurvey.de/help/doku.php/en:create:debugging

So, I read the chapter you sent and created the codes with Seriennummern and saved them in my random variable (E202). Unfortunately, it is still not displaying the additional page.

These are the debug information from the page I added to the survey between the last "normal" and the end page, where it should show the MTurk number (text element: E203)

Do you see where the problem is?

Ok, I tried it again, and it still does not work.
When I test the questionnaire starting from my last "normal" page, it shows the MTurk page with a generated code. That's perfect :)
BUT if I start the questionnaire from the beginning, it does not show the MTurk page, but goes from the last "normal" to the end page...

> %code% = (text) AW597458

That looks good so far. Does ths page with the debug information show E203 at all? You have probably some more text than just the code (placeholder)?

> BUT if I start the questionnaire from the beginning, it does not show ...

Please double-check the debug information. Is that complete or is there anything else? You can also start an interview in debug mode and when you're on the MTurk page, simply post the URL from the browser's address bar. Then I can check for possible problems in the HTML structure of the text element.

This is the debug information from the last "normal" page when I start from the last "normal" page:

I am sorry, but I do not know what should be wrong here... :(

How can I give you access to the debug version of the interview?

> This is the debug information from the last "normal" page ...

Obviously, different questions are displayed on this page, depending on where you start. In the first case, these are VI09 and VI06, in the second case they are VI02 and VI03. According to the debug information, I assume that a setPageOrder() was active here.

Now the interesting part: What is show in the debug information when you pressed "next" in the second case?

Hi,

yes, so the content on the last "normal" page is randomised. I used set page order to avoid material being shown twice when people refresh the page.

Last "normal" page when started from the beginning:

Answer 1

Thanks for the debug information. I think this here is the explanation:

[Processing]    Reading answers from page 10
...
[Information]    According to the previously set page order, the last page of the questionnaire is shown

As you already noted, nothing about the rendom geneator shows up. Why? Because page 11 that contains the random generator is skipped by setPageOrder().

You have not yet posted the PHP code from the setPageOrder(), but I assume that you added 'end' to the page order (after doing the randomized paged), which is the goodbye page. Pleaseg ive page 11 an ID and add this ID instead of 'end'.

Hi, thank you so much! I changed 'end' to where it says 'MTURK' now. And it works :)

//06 CONTROL
// Video Rotation
if (!isset($video)) {

$video = array(
    'Video A', 'Video B', 'Video C', 'Video D', 'Video E'
);
shuffle($video);
put('VI11_01', $video[0]);
put('VI11_02', $video[1]);
put('VI11_03', $video[2]);
put('VI11_04', $video[3]);
put('VI11_05', $video[4]);
 registerVariable($video);

$i = loopPage(count($video));
text($video[0], 'align=center', 'spacing=30');

}

question('VI01');  // RATING1
