You have created the object on Master page that causing the issue also
missed the 'presence' after object name. I redesign the form but not on
master Page and apply the below script and its workingClick event of
'Nee' radio buttonif(this.rawValue == 1) {
xfa.form.form1.subform1.sub1.presence="hidden";} Click event of 'Ja'
radio button if(this.rawValue == 1) {
xfa.form.form1.subform1.sub1.presence="visible"; }For more info refer
the below screenshot.
