Export html NameError: name not defined (even though already defined)

psychopy 2020.2.10
Hello all,
I’m building a JS experiment with the builder.
For the loop file, I’ve set
‘condition’ + $expInfo[‘condition’] +’.xlsx’

In experiment settings, I’ve got condition there.

but when I export html, I get following error messages:

SyntaxError: invalid syntax

the porblem is very similar to
NameError: name not defined (even though it was defined earlier) - Online experiments - PsychoPy

but the solution doesn’t work for me…

I’ve tried to use a single variable for the loop file defintion, which was coded like below

but there still comes error msg:

It would be really nice if someone could tell what’s wrong with my experiment
much much thx in advance!

Hello

try
$"condition{}.xlsx".format(expInfo['condition'])

Best wishes Jens

Alternatively, try just moving the dollar sign to the start. Does your form of formatting now work online @JensBoelte ?

Hello @wakecarter

I did not test it on-line. I took the formatting from Building Experiments in PsychoPy :grinning: :wink:

Best wishes Jens

Cozy over here :). I tried a couple of approaches for exporting to online, but none worked out. Starting to suspect that variables in conditions files isn’t supported yet for online…

You can definitely point to a variable when defining a loop online, if that’s what you mean. However, this thread contains code for doing that that I don’t recognise and feels overly complicated.

!.includes?
prompt ?

I reckon that the while loop is killing expInfo.

Hello,

I can confirm that my formatting does not work on-line. :disappointed: I just gave it a test.

@wakercarter’s solution worked. :+1:

Hello,

you might want to restrict the options a participant can chose from so that you don’t need a while-loop.

However, you need the info dialog for this.

Dear all,
thank you for your replies!
I’ve adapted the experiment setting as recommended

however, the export still doesn’t work:

with $usecsv:

thank you!
but it does not work…

but the variable “usecsv” did not work either, so I also suspected that no variables are allowed in conditions files…

oddly enough:
I wanted to create a minimal example for you,
but as soon as I put the psyexp and the xlsx files into another directory, the export worked!

Could there be some kind of “local cache” for the Psychopy builder?
Anyway, the problem is solved; thank you so much!

Best wishes,
PJ

I always use Ctrl-Shift-R when rerunning the experiment after a sync.

Which version worked? Please could you mark it as the solution if you have one?
