Removing zeros in survey response from constant sum question

Hi, I am trying to remove zeros from the constant sum questions in my survey. I used the following code to remove the prefilled zeros in the _survey_... if(jQuery(".ValidationError").text()==""){ jQuery(".InputText").val(''); } ...however, this doesn't remove the zeros from the data once the survey is completed. Is there a way to ensure that the blank responses also don't populate as zeros in the data in the data & analysis section? I don't want to have to keep exporting the data, deleting the zeros, then reimporting it for the report to calculate the proper averages in reports (not including all the zeros). Thanks
