Adobe LiveCycle Designer ES4 Need help with JavaScript Ref. Subtracting Time.

We have used the form Brake log sheet I created in Adobe Acrobat XI Pro with the current JavaScript to subtract time and it works fine.  I am still trying to learn JavaScript language so please be patient with me. I would like to create the form in designer but need to get the script working.  I imported the Acrobat form into Designer for the time being and as i have read you will have to correct some of the JavaScript but when i run it I receive no errors and it does not work so i do not know were to start working.  I would like someone to take a look at it and please help me on it.

I don't see a way to attach my PDF so ill insert the code i have.

Under Variables

function Num2sTime

function sTime2Num

function SupressZero

function Time2Num

Num2sTime


function Num2sTime(fValue) {
// convert minutes to HH:MM string
fDiff = Math.round(Number(fValue) / 60);
// get hours from fDiff
fHours = Math.floor(fDiff / 60);
// get minutes less than hour from fDiff
fMins = Math.round(((fDiff / 60) - fHours ) * 60);
// format fMins with leading zero
sMins = util.printf("%,302.0f", fMins);
// build display string
return fHours + ':' + sMins;
}




SupressZero


function SupressZero(sValue) {
if(Number(sValue) ==0) sValue = '';
return sValue;
}




Time2Num


function Time2Num(sFormat, sTime) {
/*
convert time string (sTime) with format of sFormat
to the seconds since the start of the day
*/
if(sTime == '') return ''; // exit
// get date time for Epoch date and sTime
var oTime = util.scand('mm/dd/yyyy ' + sFormat, '01/01/1970 ' + sTime);
// convert UTC Offset to milliseonds for adjustment
var fTZOffset = oTime.getTimezoneOffset() * 1000 * 60
// time since the start of the day in millseconds
var fTime = oTime.valueOf() - fTZOffset;
// convert to seconds and return value
return Math.round(fTime / 1000);
}


sTime2Num


function sTime2Num(sValue) {
if(sValue == '') return 0;
var aValue = sValue.split(':');
return (aValue[0] * 3600) + (aValue[1] * 60);
}

and in my calculate script were i place in the text Field Total_TimeRow1

event.value = '';
var sStart = this.getField('Time OutRow1').value;
var sEnd = this.getField('Time InRow1').value;
if(sStart != '' & sEnd != '') {
var fStart = Time2Num('HH:MM', sStart);
var fEnd = Time2Num('HH:MM', sEnd);
var fEnd = Time2Num('HH:MM', sEnd);
var fDiff = fEnd - fStart;
fDiff = Math.round(fDiff / 60);
fHours = Math.floor(fDiff / 60);
fMins = ((fDiff / 60) - fHours ) * 60;
sMins = util.printf("%,302.0f", fMins);
event.value = fHours + ':' + sMins;
}

I'll insert the pdf is someone can tell me how.

Thank you all for your help in this matter.
