Add quantity for expense sublist on line commit - suitescript2.0

Question

I have an expense report transaction where I am trying to sum the quantity field on the sublist and update a custom field (i.e. basically a running total that is updated every time a line is committed)
This is a part of the client script that I have so far:
function sublistChanged(context) {
var currentRecord = context.currentRecord;
var sublistName = context.sublistId;
var sublistFieldName = context.fieldId;
var op = context.operation;
totalExpQuantity = 0;
if (sublistName === "expense") {
for (var i = 0; i < sublistName.length; i++) {
var quantity = currentRecord.getCurrentSublistValue({
sublistId: "expense",
fieldId: "quantity",
});
log.debug("quantity", quantity);
}
totalExpQuantity += parseInt(quantity);
var lineCount = currentRecord.getLineCount({
sublistId: "expense",
});
console.log(lineCount);
currentRecord.setValue({
fieldId: "custbody_mileage_exp_report",
value:
"Total has changed to " +
currentRecord.getValue({
fieldId: "amount",
}) +
" with operation: " +
op +
" total quantity: " +
totalExpQuantity,
});
}
}
Every time a line is committed with a quantity value, I want the total to increment by the value of the line that was committed
i.e. here, after every line is committed, the total should go from 10,000, to 10,500 to 15,500
I have tried a variation of this code where the following line is part of the 'for loop':
totalExpQuantity += parseInt(quantity);
i.e.
for (var i = 0; i < sublistName.length; i++) {
var quantity = currentRecord.getCurrentSublistValue({
sublistId: "expense",
fieldId: "quantity",
});
totalExpQuantity += parseInt(quantity);
log.debug("quantity", quantity);
}
I get the following result:
Is what I am trying to do possible?
Where am I going wrong in the code? Should it be a different entry point?
I have also tried postsourcing though it didn't retrieve the quantity field and returned a blank
Found the answer. This is the working version of the script:
/**

define(["N/search"], function (search) {
function fieldChanged(context) {
try {
var recordObj = context.currentRecord;
var employeeObj = parseInt(
recordObj.getValue({
fieldId: "entity",
})
);
if (context.fieldId == "entity") {
var employeeName = parseInt(employeeObj);
log.debug("employee", employeeName);
var expensereportSearchObj = search.create({
type: "expensereport",
filters: [
["type", "anyof", "ExpRept"],

],
});
var searchResult = expensereportSearchObj
.run()
.getRange({ start: 0, end: 1000 });
log.debug("result", JSON.stringify(searchResult));
var searchResultCount = expensereportSearchObj.runPaged().count;
log.debug("expensereportSearchObj result count", searchResultCount);
let q = 0;

var quantity = searchResult[i].getValue(searchResult[i].columns[5]);
log.debug("quantity", quantity);
q += parseInt(quantity);
log.debug("q", q);
}
recordObj.setValue({

if (expenseCategory == 8) {

}
}
return {
