Getting and illegal character in a work hrs calculation

[Susan282836352ywm]

I am getting an illegal character error in line 7.  I'm trying to determine the number of hours worked between two time, including if the time cross over midnight.  Can you review and let me know what the error is?

if ((this.getField("End time").value.length == 0) || (this.getField("Start time").value.length == 0)) {
event.value = " 24.0";
}
else{

var time1 = this.getField(“Text1”).value;
var time2 = this.getField(“Text2”).value;

// convert to date
var datetime1 = new Date(‘1970/01/01 ‘ + time1);
var datetime2 = new Date(‘1970/01/01 ‘ + time2);

var diffInMilliSeconds = Math.abs(datetime1 – datetime2) / 1000;

// calculate hours
var hours = Math.floor(diffInMilliSeconds / 3600) % 24;
diffInMilliSeconds -= hours * 3600;

// calculate minutes
var minutes = Math.floor(diffInMilliSeconds / 60) % 60;
diffInMilliSeconds -= minutes * 60;

// set field value to the difference
event.value =hours + “:” +minutes;

var result;

if (endMin < startMin) {
var minutesPerDay = 24*60;
result = minutesPerDay - startMin; // Minutes till midnight
result += endMin; // Minutes in the next day
} else {
result = endMin - startMin;
}

var minutesElapsed = result % 60;
var hoursElapsed = (result - minutesElapsed) / 60;

alert ( "Elapsed Time : " + hoursElapsed + ":" + (minutesElapsed < 10 ?
'0'+minutesElapsed : minutesElapsed) ) ;

Sorry, Text1 and Text2 should be Start Time and End Time

Only use this quotes "" not these “”

That did correct that illegal character for line 7 but now I have one a line 14.

if ((this.getField("End time").value.length == 0) || (this.getField("Start time").value.length == 0)) {
event.value = " 24.0";
}
else{

var time1 = this.getField("End Time").value;
var time2 = this.getField("Start Time").value;

// convert to date
var datetime1 = new Date('1970/01/01 ' + time1);
var datetime2 = new Date('1970/01/01 ' + time2);

var diffInMilliSeconds = Math.abs(datetime1 – datetime2) / 1000;

// calculate hours
var hours = Math.floor(diffInMilliSeconds / 3600) % 24;
diffInMilliSeconds -= hours * 3600;

// calculate minutes
var minutes = Math.floor(diffInMilliSeconds / 60) % 60;
diffInMilliSeconds -= minutes * 60;

// set field value to the difference
event.value =hours + ":" +minutes;

var result;

if (endMin < startMin) {
var minutesPerDay = 24*60;
result = minutesPerDay - startMin; // Minutes till midnight
result += endMin; // Minutes in the next day
} else {
result = endMin - startMin;
}

In this line: var diffInMilliSeconds = Math.abs(datetime1 – datetime2) / 1000;

minus/subtraction sign is not correct.

Also, at first 'else' you opened curly brackets but didn't close it.

Seems to be working but it is not putting the data in the form field.  Have I missed a step?

[Susan282836352ywm]

I had some help in adjusting the code but it is still not placing the data in the PDF field.  Is there something still wrong with the code?

if ((this.getField("End Time").value.length == 0) || (this.getField("Start Time").value.length == 0)) {
event.value = "24.0";
} else {
var endTime = this.getField("End Time").value;
var startTime = this.getField("Start Time").value;

// convert to date
var endDate = new Date('1970/01/01 ' + endTime);
var startDate = new Date('1970/01/01 ' + startTime);

var diffInMilliSeconds = Math.abs(endDate - startDate) / 1000;

// calculate hours
var hours = Math.floor(diffInMilliSeconds / 3600) % 24;
diffInMilliSeconds -= hours * 3600;

// calculate minutes
var minutes = Math.floor(diffInMilliSeconds / 60) % 60;

// set field value to the difference
var formattedTime = endDate.toLocaleTimeString("en-US", {hour: '2-digit', minute:'2-digit'});
event.value = formattedTime;

// calculate elapsed time
var elapsedTime = ((hours + 24) - (startDate.getHours() + (startDate.getMinutes() / 60))) % 24;
var hoursElapsed = Math.floor(elapsedTime);
var minutesElapsed = Math.floor((elapsedTime - hoursElapsed) * 60);

alert("Elapsed Time: " + hoursElapsed + ":" + (minutesElapsed < 10 ? '0' + minutesElapsed : minutesElapsed));

-Where did you place the code?

-What's the point of the code after this line:

event.value = formattedTime;

?
