Javascript ist not being saved in the advanced actions

Hello,

I have a problem in Captivate 2017 with Javascript and the advanced actions. The script is not being saved and discarded when the script window is closed. It works only if I create the script as a single action.

Can someone tell me why that is?

This is my code:

var Daten = [raum_bez, pers_nam_a, pers_pos_a, pers_mail_a, pers_tel_a, pers_note_a, pers_nam_b, pers_pos_b, pers_mail_b, pers_tel_b, pers_note_b, pers_nam_c, pers_pos_c, pers_mail_c, pers_tel_c, pers_note_c, pers_nam_d, pers_pos_d, pers_mail_d, pers_tel_d, pers_note_d];

var Belegung = [["eg-3", "EDV", "Test Person", "IT Management", "test.person@web.de", "0208", "Nur nachmittags ansprechbar", "Ano Nym", "IT Management", "ano.nym@gmx.de", "0202", "Ansprechpartner für Hardwareprobleme", "John Donym", "IT Management", "john.donym@gmx.de", "0201", "Ansprechpartner für den schwarzen Peter", "Hans Mustermann", "IT Management", "hans.mustermann@gmx.de", "0200", "Ansprechpartner für Datenbanken"], ["eg-5", "Training", "Test Person 2", "E-Learning Designer", "test.person.2@gmx.de", "0118", "-", "Else Dummy", "Trainerin", "else.dummy@web.de", "0112", "-", "", "", "", "", "", "", "", "", "", ""]];

var raum = window.cpAPIInterface.getVariableValue("raum_index");

for (var i = 0; i < Belegung.length; i++) {

        if (Belegung['Index'] == raum) {

    for (var i2 = 0; i2 < Daten.length; i2++) {

window.cpAPIInterface.setVariableValue(Daten[i2],Belegung[i2+1]);

}

        }

    }
