Use document.getElementById to find your elements. Also start testing using IE if you want it to work in IE.

[gon1387]

You can use getElementById, as stbuchok's suggested, or you can also explicitly access the value through document.[YOUR_FORM_NAME].[YOUR_INPUT_NAME].value

Base on your HTML, here's the ref on your firstname's input value: document.form1.fname.value

[karlcunanan]

It works! Thanks guys! But I want to clear my mind regarding this, why is it only in IE that needs to be like that?

[gon1387]

Actually the one I'm quite unsure of is how'd you able to access the form element's value with just using [NAME].value only, in the global context; and how was it able to run in Firefox and Chrome without knowing the form's elements. What I'm trying to say is, when submit event fires up, the names it has access at, is it's own siblings only, in your case siblings of the form elements in the document's form collections. It's like this:

// when MyNameIsA is access in this context, it only knows MyNameIsA of elementA
    // and not their children
<elementA name="MyNameIsA">
    // when MyNameIsA is access in this context, it only knows MyNameIsA of subElementA
    // and not their parent's
    <subElementA name="MyNameIsA"></subElementA>
    <subElementB name="MyNameIsB"></subElementB>
</elementA>
<elementB name="MyNameIsB">
    // when MyNameIsA is access in this context, it only knows MyNameIsA of subElementA
    // in elementB, and not in elementA not its children
    // to access subElementA in elementA you should explicitly
    // call the elementA.MyNameIsA to call on elementA's subElementA
    <subElementA name="MyNameIsA"></subElementA>
    <subElementB name="MyNameIsB"></subElementB>
</elementB>

So in your case, your best bet of accessing a single form in a page is:
document.getElementById
But if you're using multiple form in a page and you think would have a chance of getting the any duplicate names, you can use:
document.forms["PUT_YOUR_FORM_NAME_HERE"]["YOUR_INPUT_NAME"].value
The reason behind this is, getElementById would get only the first element it finds using your queried ID.
and if you're arbitrarily accesing an input through submit event, get the target form and access it like this form.["YOUR_INPUT_NAME"].value if you assign the target form element the variable form.
