trials repeating

Hi,

Some of my trials repeat when they shouldn't. I think it might have to do with the way I'm selecting items- using lists and values.

Apologies, I think that the script just isn't updating on the millisecond server (it was a bug from a prior version). Any tips on that instead? Basically when I delete the files from a web script and upload the new ones, it seems to just be storing the old scripts again (I can see it's the old code when I download it).

Sorry again!

Upload the script under a different name (call it e.g. bilexmockup_fixed.iqx), and then select that new script as the start script.

Could you take the time to explain which trials repeat and why you think they shouldn't, please?

Notice here

<block study>
/ trials = [1-30 = noreplace(intro_hf_mis,intro_hf_match); 31-60 = noreplace(intro_lf_mis, intro_lf_match); 61-193 = noreplace(control, test)]
</block>

that you're trying to sample 133 (not 132) trials from control and test in equal proportions, which of course can't work out evenly.

Hi,

Some of my trials repeat when they shouldn't. I think it might have to do with the way I'm selecting items- using lists and values.
