I could do with some urgent help....
I have a constant sum table (and same issue on a constant sum matrix table).
The default choices are 0, but there is a concern is that a respondent might click next without checking their response (i.e. just keeping the 0).
So, I thought I could make the default choice blank, so that the respondent would need to enter a 0 (or another value).
I didn't seem to be able to make default choices blank on these question types, so I tried some code. On the Constant Sum Matrix table I did:
Qualtrics.SurveyEngine.addOnload(function() {
jQuery("#"+this.questionId+" td input[type=text]").val("");
});
This does change the default choice to blank - however, if I click next, I'm still able to proceed without changing the blank to a 0 or another number.
Any thoughts please..
I need to do this for two question types (Constant Sum/ Matrix Table Constant Sum).
Thank you

Hi MikeW ,
If you want to stick with the Constant Sum question type, you can use Custom Validation to require an entry in each field. It would look something like this:
Another option is to use the Matrix Table with Text Entry instead of Constant Sum Type, and add use the Force Response and Number Content Type settings.

https://community.qualtrics.com/XMcommunity/discussion/comment/44119#Comment_44119Hi MatthewM - thanks - that works for the Matrix Constant Sum questions.
Did you have any thoughts on how I do the same on a standard Constant Sum question? I don't appear to be able to clear the answers with JavaScript on the standard Constant Sum??
+30Instead of using a Constant Sum question, you could use a Matrix with a single column.

On the Matrix Constant Sum... I'm using the code below to make the default choices blank and then your custom validation idea to ensure that respondents answer.... however, once the validation is triggered, it re-loads the question and any answers the respondent did give are blanked off again by the code. Is there a way to avoid that?
Qualtrics.SurveyEngine.addOnload(function() {
jQuery("#"+this.questionId+" td input[type=text]").val("");
});
+30Unfortunately I'm little better than a novice with Javascript. But if you make the question a Matrix Table with Text Entry, and add use the Force Response and Number Content Type settings, the fields should be blank by default, instead of having 0 prepopulated like it is with Constant Sum question types.
