Cannot access checkbox element

[darran]

I did a form, I created a checkbox under the same name 'lead_role' but I can't seem to access it in my javascript validation.

This is the code in my HTML page
<input name="lead_role " id="lead_role" type="checkbox" class="style30" value="1">

And this is the validation I am testing out
alert(document. form1.lead_role .checked);

My browser returns me an 'undefined' alert message.

The only way I was successful in accessing the element is using the getElementById( ) method but that only gets the very first instance of the checkbox.

Can anyone help me out? Thanks :)

lead_role is an array of checkboxes, so loop through, e.g. the third checkbox checked value can be accessed by:

document.form1.lead_role[2].checked
