Weekly TimeSheet client script totalHours not refresh in direct

Hello,

I have a question when i use a client script on time sheet, i use this ==>

var timesheetRecord = scriptContext.currentRecord;

var totalHours = timesheetRecord.getValue('totalhours');

But when i log it this variable totalHours , i don't have the current value but i have the previous save value on the record and not the value in direct.

can i do a refresh in my script for take the good value i direct before save it ?

function saveRecord(scriptContext) {

var timesheetRecord = scriptContext.currentRecord;

var totalHours = timesheetRecord.getValue('totalhours');

log.debug({

title : 'totalHours',

details : totalHours

});

if (Number(totalHours) > 39) {

dialog.alert({

title : 'Alert',

message : 'Le temps total saisie est supérieur de 39'
