Error with online experiment-stuck on initilising

[wakecarter]

Which code do you mean?

Your error implies that you have a variable that you are using to open Groupx.xlsx but something has gone wrong with your definition of x so it is coming out as undefined.

@wakecarter

randint = function(min, maxplusone) {
  return Math.floor(Math.random() * (maxplusone - min) ) + min;
}

code_2 Begin Experiment

conditions = "ABC"
condition2=conditions[randint(0,3)]

This one. I defined my loop as ‘Group’+conditions2+‘.xlsx’. For conditions2, I am trying to randomly select between A, B, or C as my excel files are named as GroupA, GroupB or GroupC. I know how to do it in Python but I am confused about the javascript. Can you help me? Thank you!

[wakecarter]

That looks fine so I would use the print / console log option to work out which step is failing.

[Qiushan_Liu]

The code components looked like this.

The loop look like this.
When I am running online, as I get to the step with the loop, the condition file was unable to be selected. Please let m know if this is a clear description or if further clarification is needed. Thank you again for your help!

[wakecarter]

Have you checked the value of conditions2 straight after you set it?

[Qiushan_Liu]

I am not sure what you mean by this.

[wakecarter]

Did you find the bit about the browser console in my crib sheet?

[Qiushan_Liu]

The code you provided seems to be working and an excel file was selected. However, I am still running into the same error. I am going to see if I could figure out what is causing this error.

[wakecarter]

Which routine is the code component in? I assume it’s in a Begin Experiment tab but my guess is that it also needs to be in a routine that comes earlier than the loop it is randomising.

[Qiushan_Liu]

Ah, I put the code component in the routine under the loop. I am going to try to put the code component earlier and see if that is what is causing the trouble, thanks!

[Qiushan_Liu]

That was the exact issue! I added the code component before the loop and it worked nicely! Thank you so much for your help!

Hello,

I am having an issue with my online script as well. Everything is uploaded online but I am not able to pilot it since it is stuck on “initializing the experiment”
