For the first part, the script really should be:
event.target.setItems([
this.getField("Name1").value,
this.getField("Name2").value,
this.getField("Name3").value,
this.getField("Name4").value]);
Although it's not clear where you placed that script, so it might be better to place it elsewhere.
The other problem is difficult to diagnose without being able to see the file and how things are set up.
