Add the csmAddTotals function to the survey header to make it available to any question in the survey. Go to Look & Feel → General → Header edit → and paste the provided csmAddTotals function JS:

<script>/*Paste csmAddTotals function JS here*/</script>

Alternatively, paste the csmAddTotals function JS into a question's JS outside the existing Qualtrics functions to make it available to questions on the page.

Add JS to call the csmAddTotals function to apply it to the matrix question as follows:

Qualtrics.SurveyEngine.addOnload(function() {
	csmAddTotals(this);
});

To override the default options, specify the desired options in the second function argument as an object. For example:

Qualtrics.SurveyEngine.addOnload(function() {
	csmAddTotals(this,{grandTotal:false});
});

grandMustTotal is a number greater than 0 (zero) that the grand total must add to when grandTotal is true. When the grand total is not equal to grandMustTotal the next button is disabled and the grand total is displayed in red. When the grand total is equal to grandMustTotal the next button is enabled and the grand total is displayed in green.

Default: 0
