Reply To: Using if statements during a trial

[mschrumpf]

Hello everybody,
I am currently working on a very similar experiment: a self-paced reading task where some but not all of the items have a comprehension question.
I tried to apply your code from earlier in this thread, Jeremy, as stated below. My implementation has completely taken out the skript however, as I now only get the “There must be some items in the running order” error message when I try to run it.
This is my code:

Template( "MyTable.csv" ,
    row => newTrial( "experiment" ,
        dashed("sentence", row.Satz)
        ,
        newButton("Fertig")
            .print()
            .wait()
        ,
        newTimer(200)
            .start()
            .wait()
        ,
        newText("Frage", row.Frage)
        ,
        newText("Links", row.Links)
        ,
        newText("Rechts", row.Rechts)
        ,
        newCanvas("Canvas", 450,200)
        ,
        newSelector("Selector")            
        ,
        newTimer("200", 200)
            .start()
            .wait()
        ,
        ( row.Antwort=="1" ? [
            getText("Frage")
                .print(),
            getText("Links")
                .print(),
            getText("Rechts", row.Rechts)
                .print(),
            getCanvas("Canvas")
                .add(   0 , 0 , getText("Links") )
                .add( 250 , 0 , getText("Rechts") )
                .print(),
            getSelector("Selector")
                .add ( getText("Links"), getText("Rechts"))
                .keys(          "F"     ,           "J")
                .log()
                .once()
                .wait()
            ] : [
            getText("Frage")
            .print() //Placeholder code. The final skript should just "do nothing" here
                ] )
    )
    .log("Item" , row.Item )
    .log( "Konsistent" , row.Konsistent )
    .log( "Geschlecht" , row.Geschlecht )
    .log( "Krit" , row.Krit )
    .log( "Anzahl" , row.Anzahl )
    .log( "Antwort" , row.Antwort )
    .log( "Satz" , row.Satz )
    .log( "Frage" , row.Frage )
    .log( "Links" , row.Links )
    .log( "Rechts" , row.Rechts )
)

Since the error message is giving me nothing to work with, I would be very grateful for any hints as where I have gone wrong.
Thanks in advance and best regards
