Description*
This JavaScript function uses a global variable listSize which is computed from the formula @Elements(someList). The list is really an array of <INPUT> fields called total and quantity.

Because the fields are created with the HTML <INPUT> tag, a Notes field called total and one called quantity will be necessary on the form or the Domino server will not allow you to submit it. Also note that the calculated values are stored in three fields on the form: subtotal, totalsList, and qList.

function calcSubtotalColumn ( ) {
var subtotal = 0;
var subtotalList = "";
var qtyList = "";

if (listSize == 1) {
subtotal = makeIntoNumber(document.forms[0].total.value);
subtotalList = document.forms[0].total.value;
qtyList = document.forms[0].qty.value;
}
else {
for (i = 0; i < listSize; i++) {
subtotal = subtotal + makeIntoNumber(document.forms[0].total[i].value);
subtotalList = subtotalList + ";" + document.forms[0].total[i].value;
qtyList = qtyList + ";" + document.forms[0].qty[i].value;
}
}
document.forms[0].subtotal.value = formatAsCurrencyString( subtotal );
document.forms[0].totalsList.value = subtotalList;
document.forms[0].qList.value = qtyList;
return;
}
