`$(questionid="QID2")` finds the div with the id of QID2. That is not the same thing as the question object (i.e., the "this" in this.setChoiceValue) .

Thanks for the fast reply, Tom. How would I properly reference the question object to execute setChoiceValue? I guess I need to use something like:
questionId = ????
Qualtrics.SurveyEngine.registry[questionId].setChoiceValue(i, false);

So far all approaches to assign the questionId of the other question haven't worked. Can you help?

---

As far as I can tell, the question object (i.e. registry) isn't accessible from another question. Therefore, you can't apply setChoiceValue to a different question. You can do it directly through the DOM:
```
jQuery("#QID2 input").prop("checked", false);
```

Unfortunately this solution is not working either. I tried all combinations but no success. I kept getting all kinds of errors.

Please post your code.

The code looks like this. What I try to do, is show and hide question QID2 and QID32 based on the selection of choices of the questions with the Javascript. In addition, I want to make sure that all selections are reset when hiding it. It won't work with display logic as I have quotas on the choices. I thought this is an easy thing but I already sitting since to days on it.

```javascript
Qualtrics.SurveyEngine.addOnload(function()
{
Reset();
this.questionclick = function(event,element){
Reset();
if (event.target.value == 1) {
$(questionid="QID2").show();
}
if (event.target.value == 2) {
$(questionid="QID32").show();
}
}
});

function Reset() {
$("QID2 input").each(function(i){
this.prop("checked", false);
});
$(questionid="QID2").hide();
$(questionid="QID32").hide();
}
```

Replace $ with jQuery. $ in Qualtrics refers to prototypejs.

Thanks for the info. I now get the code running without errors. But it still doesn't deselect the radio buttons. I also attach the project as I'm totally out of ideas to fix this.
