/ errormessage = true(errorMark, 0)

needs to read

/ errormessage = true(errorfeedbacksound, 500)

Also, a <trial> may only have a single /errormessage and a single /correctmessage attribute, not mulltiple. You may, however, define multiple /responsemessage attributes.

No.

Hi Dave, thanks a lot for the last answer!
I have some follow up questions.

Is it possible to have and an error message and sound at the same time with the responsemessage  feature?

Furthermore, I was wondering if you can programme in the openended trial that when the participants press the ESC button the expt (so not the script) quits. If I understand correctly the scancode for the ESC-key is 1. However, now the expt ends when you press 1 and the ‘nextbutton’.
See part of the script below.

Thanks in advance!

Yes.

No. The only thing you can do is have the participants type some special word (e.g. "quit") into the openended's textbox and then /stop based on that.

<expt>
/ stop = [openended.testc.response == "quit"]
...
</expt>

Hi dave, 
Thanks again for the answer, that really helps a lot. 

I however cannot figure out how to use / responsemessage to play an errorsound and errormessage.
This part of the script is in the first comment.

Furthermore, I came across another problem. 
I have 3 blocks that branch and thus repeat after each other. 
I want them to stop after 20 minutes. 
This is tried to program this with the timeout function, however this does not work. 
Then I tried to branch the experiment after 20 minutes.
The elapsed time of the experiment does not seem to be correct in my output.
It shows an amount of time that is way to long.
Do you know a solution to this problem?
This part of the script is bellow.

Thanks in advance. 
Johanne

You need to define a /responsemessage attribute for every response that is *not* a correct response.

To terminate the procedure after 20 minutes, try defining /stop attributes at the <expt> level, i.e. something like

<expt>
/ stop = [script.elapsedtime >= 1200000]
...
</expt>
