Issue with javascript

Hey everyone, I've got this slight problem with my code in javascript and I cant solve it to save my life and I don't really want to mess more things around incase it makes it worse.

For some reason, when I click "get age" it just doesnt run, but the if statements seem to be running, any help would be appreciated



<script type = "text/javascript">

function dIM(Y, M) {
with (new Date(Y, M, 1, 12)) {
setDate(0);
return getDate();
}
}
function dateDifference(birthdate1, birthdate2)
{
var year1 = birthdate1.getFullYear(), month1 = birthdate1.getMonth(), day1 = birthdate1.getDate(),
year2 = birthdate2.getFullYear(), month2 = birthdate2.getMonth(), day2 = birthdate2.getDate();

if (day1 < day2){
month1--;
day1 += dIM (year2, month2);day
};
if (month1 < month2) {
year1--;
month1 += 12;

}

return [year1 - year2, month1 - month2, day1 - day2];
}

function ageCalculator() {

var day = document.age.inputdate.value;
var month = (document.age.inputmonth.value - 1);
var year = document.age.inputyear.value;

var now = new Date();
thisday = now.getDate();
thismonth = now.getMonth();
thisyear = now.getFullYear();

var first = new Date(thisyear, thismonth - 1, thisday);
var second = new Date(year, month - 1, day);
var yourage;
var datediff;

if (day == "" || month == "" || year == "")
{
alert ("Please fill in all of the boxes before getting your age");
}

else if ((day != parseInt(day)) || (month != parseInt(month)) || (year != parseInt(year)))
{
alert ("Please only enter digits in the day, month or year boxes"); return false;
}

datediff = dateDifference(first,second);

if ((thismonth < month) || (thismonth == month & thisday<=day)) {thisyear--;}

yourage = thisyear-year;

var next = parseInt(year)+datediff[0]+1;
var difference = Date.UTC(next, month, day, 0, 0, 0) - Date.UTC(thisyear, thismonth, thisday, 0, 0, 0);
var daysleft = difference/1000/60/60/24;

document.age.daysremaining.value = daysleft+" days left for your next birthday";
document.age.ageoutput.value = yourage;

}

function clear(form){
form.Result.value = "";

}
</script>
<center>
<p>
<form name = age>
<p>Day of birth&nbsp;&nbsp;&nbsp;&nbsp;
<input type="text" id="inputdate" size="2"><br/>
Month of birth&nbsp;
<input type="text" id="inputmonth" size="2"><br/>
Year of birth
<input type="text" id="inputyear" size="4" ><br/>
<input name="button" type="button" id="button2" onClick="ageCalculator()" value = "Get Age"/>
<input type="reset" name="Reset" id="button" value="Reset" />

</p>
<p> You are
<input type = "text" name = "ageoutput" size = "4" value = "0"> years old
<input type = "text" name = "daysremaining" value = "0" />
</p>
</form>

This has nothing to do with your question but <form> needs an action, name is deprecated, id is used instead, and the attributes should be in quotes.
So, <form name = age> S/B <form id="age" action="some action">.

A trouble shooting tip use alert('here');die; as the first line in a function to see if your getting there. In this case you are. Next trouble shooting tip Check your inputs. So I put alert(day);die; after var day = document.age.inputdate.value;
I got nothing. If I got an alert box I would know the data was wrong but nothing means the line(code) is wrong. Changed it to var day = document.getElementById('age').inputdate.value; Got the alert.:thumbsup:

Thanks for the help, I did the corrections but unfortunately I still can't get it work, thanks anyways.

If anyone else can solve this, I'd be very grateful :D

You should post your new code

It works for me in IE9 and correctly calculates my age.

The with statement is very unreliable, is deprecated and generally discouraged, and may cause problems in other browsers.
