I have a page that allows you to input data into two input text fields. I then need to loop through the amount of input text boxes on the page and add the values together. So if someone enters 3 and 1, I need a message box that returns 4 in addition to adding the informaiton to the cookie. It’s part of a shopping cart code I previously had working but I did somehting and now it can’t recognize the form to loop through it. Does it matter where a form is defined?

The source can be seen at…

Unfortunately none of the images or the menu graphics show up…hopefully someone can help with the Javascript and form definition.

I think it may have to do with where I define the form, but I don’t know…

All of my hair is on the ground form (bad pun?) pulling at it!

@steelersfan88Mar 19.2004 — This might be IE only, but try:[code=php]<script type="text/javascript">

function getSum() {
var theSum = new Number()
for(var i=0;i<document.myForm.elements.length;i++) {
if(document.myForm.elements[i].type == "text") {
theSum += new Number(document.myForm.elements[i].value)
}
}
alert(theSum)
}

</script>

<form name="myForm">
Number 1: <input type="text" id="num1"><BR>
Number 2: <input type="text" id="num2"><BR>
Number 3: <input type="text" id="num3"><BR>
Number 4: <input type="text" id="anothernum4"><BR>
<input type="button" value="Calc Sum" onclick="getSum()">
</form>[/code]Don't ask me about cookies, I am totally against using them.

You said it yourself, let me add the word very to it, very bad...
