I'm planning to pass my participants from Qualtrics through to Inquisit Web 4, which I've previously done successfully, passing Qualtrics ResponseID through the URL.

So far, so good.

However, I've now run into a problem because in my next study I have 3 inquisit scripts that I want to run in different orders. Previously I've used the "/ subjects = (1 of 6)" format, but this doesn't work on the alphanumeric participant ResponseID code that Qualtrics generates. I can't work out how to assign a numeric code in Qualtrics, so any suggestions on how to get this randomization working would be helpful. The first two batch elements of my web file are below.

<batch>
/ file = "AMP_EXPL v4_48.iqx"
/ file = "AMP_IMPL v4_48.iqx"
/ file = "global.iqx"
/ file = "demographic.iqx"
/ subjects = (1 of 6)
</batch>
