In the ch6_examp9.htm code, my month menus show up with no "Feb" and two entries for "Mar". Any idea why that could be?

A bug, maybe? ;)

Sorry, couldn't resist. Can you post your code so we can take a look at it?

Cheers,

Maybe you can spot a mistake I'm overlooking. When I downloaded the master code from Wrox it did the same thing.

----------

JavaScript functions...

function writeMonthOptions() {
    var theMonth;
    var monthCounter;
    var theDate = new Date(1);
    for (monthCounter = 0; monthCounter < 12; monthCounter++) {
        theDate.setMonth(monthCounter);
        theMonth = theDate.toString();
        theMonth = theMonth.substr(4, 3);
        document.write("<option value=" + theMonth + ">" + theMonth);
    }
}

function recalcDateDiff() {
    var myForm = document.form1;
        var firstday = myForm.firstDay.options[myForm.firstDay.selectedIndex].value;
        var secondDay = myForm.secondDay.options[myForm.secondDay.selectedIndex].value;
        var firstMonth = myForm.firstMonth.options[myForm.firstMonth.selectedIndex].value;
        var secondMonth = myForm.secondMonth.options[myForm.secondMonth.selectedIndex].value;
        var firstYear = myForm.firstYear.options[myForm.firstYear.selectedIndex].value;
        var secondYear = myForm.secondYear.options[myForm.secondYear.selectedIndex].value;
        var firstDate = new Date(firstDay + " " + firstMonth + " " + firstyear);
        var secondDate = new Date(secondDay + " " + secondMonth + " " + secondYear);
        var daysDiff = (secondDate.valueOf() - firstDate.valueOf());
        daysDiff = Math.floor(Math.abs((((daysDiff / 1000) / 60) / 60) / 24));
        myForm.txtDays.value = daysDiff;
        return true;
}


and the HTML for the month pull-down menu...

<select name="firstMonth" size="1" onchange="return recalcDateDiff()">
    <script language="JavaScript">
        writeMonthOptions();
    </script>
</select>

I just copied and pasted the code in anew page, opened it in my browser, and I get 12 items, one for each month....

What happens when you comment out thus line:

theMonth = theMonth.substr(4, 3);

Cheers,
