> Thanks for the reply! When I add these information to the scriot, do I leave the predefined field for the forward link in the edit section of the experiment free?

Yes, you can leave it free. When setting the finish page via the script itself, this would override anything put there anyway.

> Moreover, does the '4' in [if (mod(script.groupid, 4) == 1)... refer to the 4 options?

Yes, it refers to the four different conditions / options. If you only have two, you would take the group id modulo 2.

I assume you pass the participant in via a query parameter as well and have the script(s) use it as its subject id. If so, you can "reconstruct" that information in the outgoing links you set. See e.g. this example: https://www.millisecond.com/forums/FindPost16887.aspx

> a study ID (which are contained in the entry link) will be forwarded to the respective link.

You should be able to reconstruct that based on the passed in group id.

Thanks for the quick reply!

Unfortunately I can't find the information concerning the "reconstruction" in the link you mentioned (https://www.millisecond.com/forums/FindPost16887.aspx).
Do you have another link for that?

Thanks,
Carolin

this is the relevant part from the linked thread. It reconstructs the 'id' parameter.

Hello Dave,

where exactly in the script do I add these information:
<expt>
/ onexptbegin = [if (mod(script.groupid, 4) == 1) {defaults.finishpage = "http://www.example.com/"}; ]
/ onexptbegin = [if (mod(script.groupid, 4) == 2) {defaults.finishpage = "http://www.google.com/"}; ]
/ onexptbegin = [if (mod(script.groupid, 4) == 3) {defaults.finishpage = "http://www.yahoo.com/"}; ]
/ onexptbegin = [if (mod(script.groupid, 4) == 0) {defaults.finishpage = "http://www.bing.com/"}; ]
/ blocks = [1=myblock]
</expt>

Apparently I can't find the right spot in my script :-/
Thanks!

Suppose you have two groupids. Groupid equal to 1 indicates that the participant came from referral site A. Groupid equal to 2 indicates that the participant came from referral site B. I.e.

Site A -> http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=someuniqueidentifier&groupid=1&studyid=a
and
Site B -> http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=someuniqueidentifier&groupid=2&studyid=b

Depending on where they came from, you want to to send them back to either Site A or B, and pass on the subjectid and studyid contained in the original link.

You do
<expt>
/ onexptbegin = [if (mod(script.groupid, 2) == 1) {defaults.finishpage = text.url.item.1}; ]
/ onexptbegin = [if (mod(script.groupid, 2) == 0) {defaults.finishpage = text.url.item.2}; ]
...
</expt>

with

<item urlitems>
/ 1 = "http://sitea.com/?subjectid=<%script.subjectid%>&studyid=a"
/ 2 = "http://siteb.com/?subjectid=<%script.subjectid%>&studyid=b"
</item>

Thanks for the reply!
This is working now...however it only works when participants complete the task. If they quit the task earlier with Ctrl Q they get forwarded to the page that I entered in the inquisist script manager. Is it possible to still forward them to the questionnaire they came from when the quit the task earlier?

Many thanks in advance!
Carolin

If you set the URL to redirect to at the very beginning as in the example (/onexptbegin), they should be redirected properly even if they quit early. Alternatively, why not provide the URL to the questionnaire in the web experiment's settings (what you refer to as "script manager," I think) as well? I.e., why is the URL you entered there a different one?

I solved it! Thank! The /onexptbegin command was not at the very beginning.
Regarding your question: the participants come from 2 different webpages and need to be sent back to the one they came from after the inquisit task. That's why there was another URL in the web experiment setting, at least for one group.

Hello Dave, although the other issue is solved now this problem still occurs:
I want to refer my participants to two different webpages after the inquisit task, depending on the web page they came from.
I am pretty sure that I adjusted everything as described by you. However, sometimes participants get forwarded to the correct link and sometimes they get forwarded to the wrong link. What could be wrong?
Please see below the important parts of my script:

Site A: http://research.millisecond.com/carolinmuschalik/singlecategorypictureiat_rood_vlees.web?subjectid=123&study=999&groupid=1

/ onexptbegin = [if (mod(script.groupid, 2) == 1) {defaults.finishpage = text.url.item.1}; ]

It would be great if you could help me with that!
Thanks in advance!

Could you please show me the data you based this conclusion on?

And, for what it's worth, you can simplify your code and get rid of the 1st <expt> element:

<expt>
/ onexptbegin = [defaults.finishpage = text.url.item.1; ]
/subjects = (1 of 2)
/groupassignment = groupnumber
/ blocks = [1=practice_compatibletest; 2=compatibletestinstructions; 3=compatibletest;
 4=practice_incompatibletest; 5=incompatibletestinstructions; 6=incompatibletest; 7=summary]
/onexptend = [values.completed = 1]
</expt>

<expt>
/ onexptbegin = [defaults.finishpage = text.url.item.2; ]
/subjects = (2 of 2)
/groupassignment = groupnumber
/ blocks = [1=practice_incompatibletest; 2=incompatibletestinstructions; 3=incompatibletest;
4=practice_compatibletest; 5=compatibletestinstructions; 6=compatibletest; 7=summary]
/onexptend = [values.completed = 1]
