You should pass the group number in via a URL query parameter. Suppose your <batch> script looks something like this:

// A
<batch>
/ subjects = (1 of 4)
/ groupassignment = groupnumber
/ file = "a.iqx"
</batch>

// B
<batch>
/ subjects = (2 of 4)
/ groupassignment = groupnumber
/ file = "b.iqx"
</batch>

// C
<batch>
/ subjects = (3 of 4)
/ groupassignment = groupnumber
/ file = "c.iqx"
</batch>

// D
<batch>
/ subjects = (4 of 4)
/ groupassignment = groupnumber
/ file = "d.iqx"
</batch>

Let's take participant number 1 in your table. For the first week / first session, you'd give her/him a link that executes the 1st <batch> condition:
http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=1

For the first week / second session, you'd give her/him a link that executes the 2nd <batch> condition:
http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=2

For the second week / first session, you'd give her/him a link that executes the 3rd <batch> condition:
http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=3

And finally, for the second week / second session, you'd give her/him a link that executes the 4th <batch> condition:
http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=4

This results in the desired order for participant 1 for the 4 sessions: A -> B -> C -> D.

Adjust the order of the conditions -- i.e. the value of the groupid query parameter -- accordingly for the other participants, i.e. participant number 2 would get the following:

1st week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=4
1st week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=1
2nd week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=2
2nd week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?groupid=3

That is D -> A -> B -> C.

Does that clarify?

And if I were you, I'd actually pass in *both* the subject id as well as the group id via query parameters. I.e.

Participant 1:
1st week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=1&groupid=1
1st week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=1&groupid=2
2nd week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=1&groupid=3
2nd week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=1&groupid=4

Participant 2:
1st week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=2&groupid=4
1st week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=2&groupid=1
2nd week / 1st session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=2&groupid=2
2nd week / 2nd session: http://research.millisecond.com/yourusername/yourexperimentname.web?subjectid=2&groupid=3

Hi Dave, 

Ive managed to reprogram it and it all seems to be working. Thanks. 

However, i dont understand one aspect. My program runs through a <batch> and uses the group number to assign which test the participant should be doing so i can follow a pattern similar to this. 



I've followed the webwizard and i presume I'm not fully understanding this part (below) as when they go to do the test it only participant number, not their group number. 




Any help would be great. 

Kind Regards

Zoe

Ahhh don't worry silly mistake on my part.

Hi Dave, 

Wonder if you can help. I editted them all and now i'm getting this error. Any ideas?

Thanks

Zoe

Thanks Dave,  I'll start working through them. 

Inquisit 4 compatible versions of both the Stroop and the Digit Span are available in the library, so I would recommend you use those either as guidance for the necessary modifications or as basis for re-implementing your changes (it's not clear to me how extensively you may have modified the originals). Eyeballing the situation, It does not make sense to try and downgrade your existing Stroop script, using the Inquisit 4 compatible version available in the library instead should be the easier option.

Your existing Digit Span script, on the other hand, doesn't look like it requires major changes to work under Inquisit 4 (see attached).

As for the remaining scripts, I suggest you download and install Inquisit 4 Lab on your computer and then work through them one-by-one. The error messages and warnings when you validate a given script in Inquisit 4 will point you to any problematic syntax sections. If you can't make sense of a particular error, let me know here and I'll try to assist.

Thanks for the details and for having a look through. 

The attached is the full test "Zoe De Grussa - Batch Run.iqx is the lead file. I quickly had a look at it in 4 and i see what you mean. The main two that i think i will struggle with is the "stroop" and the "digitspan" as i've used a number of parameters here.

But any feedback on the tests would be great.

Thanks Dave.

respectively.

To what extent you would have to edit your scripts to be compatible with Inquisit 4 depends on the extent to which you used syntax features introduced with Inquisit 5 / not avaliable under Inquisit 4. You would have to replace those with Inquisit 4 syntax equivalents (in so far as any exist). For example, Inquisit 4 has no <parameters> element, you would have to use <values> instead. If you attach your script (click +Insert -> Add File) I can give you a more concrete overview of what you need to change and how.
