Hi,

I have uploaded a zipped dot-prob program file to Jatos . After one trial, this message appeares:

Please could you kindly advice how to fix the error?

Peace,

Hi Masoud,

This error by itself is not informative. But you can find information about how to debug OSWeb experiments here:

• https://osdoc.cogsci.nl/3.3/manual/osweb/#debugging

In a nutshell, first make sure that the experiment runs on the desktop. And also make sure that you're running the latest version of OSWeb (currently 1.3.7). Then, if the experiment still crashes, you can post the error message here, taken from the browser console as described under the link above.

Cheers!

Dear Sebastian

Thanks for the reply.

The program runs well in the OS but not on the browser.

Please have a look at a copy of the 7 error messages:

Can you attach the experiment here?

Hi Masoud,

Right, I see. You're using Python-style conditional statements and these are not supported by OSWeb. Fortunately, you should be able to rewrite them to regular OpenSesame-style conditional statements. For example (Python style):

=var.correct == 1

Would become (OpenSesame style):

[correct] = 1

Hope that's useful!
