Hello,

Please try using adding the following script in the "CSS and Javascript" tab of your form:
<script type="text/javascript">
function perC(){
	fields = new Array("field1","field2","field3");
	total =0;
	for (i=0;i<fields.length;i++) 
		if (document.getElementById(fields[i]).value != '') total = parseInt(total) + parseInt(document.getElementById(fields[i]).value);
	document.getElementById('total_field').value = total;
	if (total != 100) alert('The value of the total field must be 100!');
}
</script>

In order to trigger this script when the user switched the focus from the last field that is added to the total you will need to add the following line in the "Additional attributes" property of the field:
onblur="proC();"
