Millisecond Forums

I am currently collecting data with inquisit web.
Everything had been working fine so far, but now some of the participants always get the error " Redefinition of event 49." and can't complete the experiment.
Does anyone know why this might be happening?

The script element where the error occurs is called: ba_syntax06.iqx.trial.Auswahl.stimulustimes
This should be the following part of the syntax.
(For understanding: I have recreated a Likert scale, so that I can measure the exact answer latency and after the rating of one item the next one comes directly, without having to click further).

<trial Auswahl>
/ ontrialbegin = [values.select=list.Perspekive_Auswahl.nextvalue]
/ ontrialbegin = [if(values.select==1){values.bild_selector=list.Auswahl_Frau_Bild.nextvalue}else{
    values.bild_selector=list.Auswahl_Mann_Bild.nextvalue}]
/ stimulustimes = [0= text.Einleitung; 0=text.Geschlecht; 1000=list.Bild; 1010=xAchse1, shape.kasten1, shape.kasten1a, text.kasten_1,
shape.kasten2, shape.kasten2a, text.kasten_2,
shape.kasten3, shape.kasten3a, text.kasten_3,
shape.kasten4, shape.kasten4a, text.kasten_4,
shape.kasten5, shape.kasten5a, text.kasten_5,
text.Attraktivität_Beschreibungen_U, text.Attraktivität_Beschreibungen_A]
/ validresponse = ("1", "2", "3", "4", "5")
/ beginresponsetime = 1000
</trial>


Thanks in advance for any help you can offer!
