You can use the calculation option 'the field is the ____ of fields:' and select the check boxes to be summed.

You can enter the check boxes names in the simplified field notation as long as their names comply with the naming restriction of that option. Field names must start with a an alphabetic character and spaces or dots need to be preceded by the JavaScript escape character, "\".

Or write a custom calculation script to loop through the fields and exclude any fields with a value of 'Off' from your calculation.

Pretty hard to do without the field names, since Acrobat JavaScript is an object orientated language, and form fields are a type of object.

// document level function or placed in custom calculation script
function Sum (aFields) {
var nSum = 0;
var sValue = '';
for(i = 0; i < aFields.length; i++) {
sValue = this.getField(aFields[i]).valueAsString;
if(!isNaN(sValue) & sValue != "") {
nSum += Number(sValue);
} // end if number or not null
} // end for
return nSum;
} // end Sum


// custom calculation script
// place field names as need into array
var aNames = new Array("Number.0", "Number.1", "Number.2",
"Number.3", "Number.4", "Number.5", "Number.6", "Number.7",
"Number.8","Number.9")
// do not change following code
event.value = Sum(aNames);
