Hello,
I am using a word list consisting of nine words, which should appear one underneath another (simultaneously). So far just one word is presented randomised on the screen. You can see my script below. 
Thanks in advance for any advice. 


<list PositiveWörter>
/items=["Heimat"; "Humor"; "Reise"; "Sonne"; "Urlaub"; "Treue"; "Party"; "Advent"]
/selectionmode = random
/selectionrate = always
</list>

<list NeutraleWörter>
/items=["Bedarf"; "Länge"; "Kader"; "Marke"; "Strecke"; "Runde"; "Handel"; "Finger"]
/selectionmode = random
/selectionrate = always
</list>

<list NegativeWörter>
/items=["Mörder"; "Leiche"; "Waffe"; "Armut"; "Panik"; "Falle"; "Verlust"; "Unfall"]
/selectionmode = random
/selectionrate = always
</list>

<item WortlisteEnkodierung>
/ 1 = "Heimat"
/ 2 = "Humor"
/ 3 = "Reise"
/ 4 = "Sonne"
/ 5 = "Urlaub"
/ 6 = "Treue"
/ 7 = "Party"
/ 8 = "Advent"

/ 9 = "Bedarf"
/ 10 = "Länge"
/ 11 = "Kader"
/ 12 = "Marke"
/ 13 = "Strecke"
/ 14 = "Runde"
/ 15 = "Handel"
/ 16 = "Finger"

/ 17 = "Mörder"
/ 18 = "Leiche"
/ 19 = "Waffe"
/ 20 = "Armut"
/ 21 = "Panik"
/ 22 = "Falle"
/ 23 = "Verlust"
/ 24 = "Unfall"
</item>
