==================
I have a survey and I want to randomise participants to one of 4 question groups (the last 4 question groups in the attached file).

At the moment, I have a hidden Equation question in the instructions question group (so before all the 4 I want to randomise between), the question field contains the following: {random=rand(1,4)}

I then set the Relevance equation for each of the 4 question groups as "random=1", "random=2", etc (without the quotation marks).

But at the moment it just takes me through each group sequentially as if there was no logic.

Any help on how to get this method to work or even alternative methods would be massively appreciated, I have searched around and tried a few different things.

Attaching a question export does not help us see the problem. Attach a survey export (.lss file) containing only the relevant questions.

Apologies - that's what I had intended to attach, please see the attached.

Additionally, your relevance equations should be "random == 1", "random == 2", etc.

I would suggest this for your equation question so it does not cet re-calculated on page reload:

That is amazing - I can confirm that has fixed the problem and it is now working as intended.

Sincere thanks for the swift and informative reply. I've now flagged the post with the tick to indicate it is solved.
