View Full Version : Problem with caculations

The following script on here is causing me problems.

I have a check box which calculates values based on criteria which I won't go into.

However I need it to calculate two fields and it isn't working on the second field. I originally had it working but not the way I needed, it was parsing the integers as strings and concatenating them instead of adding them. I tried parseInt() but only got errors here.

If someone can take a look and let me know what I can do to make it actually calculate that would be great.

The red Text is the one that isn't working properly.

Thanks,


<script type="text/javascript">
function zeroPack() {
if (document.getElementById('nopack').checked == true) {
document.getElementById('pack').value = 0;
} else {
document.getElementById('pack').value = Math.ceil(document.getElementById('invacv').value * .06);
}
document.getElementById('kkcode').value = document.getElementById('invacv').value + document.getElementById('pdi').value + document.getElementById('pack').value;
}
</script>

It would be helpful to know what those elements are. Can you elaborate as to what type of elements you are referring to in each of the getElementByID calls?

Whatever element it is, it's sure its value is a string as all field values are strings.

function zeroPack() {
var pack = document.getElementById('pack');
var invacv = document.getElementById('invacv');
if (document.getElementById('nopack').checked) {
pack.value = 0;
} else {
pack.value = Math.ceil(invacv.value * .06);
}
document.getElementById('kkcode').value = parseInt(invacv.value) + parseInt(document.getElementById('pdi').value) + parseInt(pack.value);
}
If the values can contain decimal numbers, then you need to use parseFloat() or Number() function instead of parseInt().
