Hello.

I am currently customizing the auditory digit span task: https://www.millisecond.com/download/library/digitspan/
and translating it into Japanese.
The point of customization is to add a feature of measuring response latency for each trial (from the point of digits (stimuli) presentation to that of response confirmation).
Even if I added some related codes on it, the output column of (values.rt) shows only "0" for all trials.
It would be appreciated if you could let me know how to fix this.

Here's what I added (For forward level 3)

<data>
/ columns = (~, values.rt)
</data>

<values>
~
/rt = 0
</values>

<trial f_trial3>
/ ontrialend = [
   ~
   values.rt = trial.f_trial3.latency;
    list.rt.appenditem(values.rt);
]
/ recorddata = true


GO
