These should not be passed as strings (in single quotes) if you
are wanting to pass objects. If you always want the first field on
the page you could do ...
document.forms[0].elements[0].focus();
otherwise, you need to pass the actual form and field objects.

Subject: 2 javascript questions
> 'lo there,

> I'm working on the checkout portion of a shopping cart app. First part
> of my question is about setting the focus to the first element of the
> form. I have some code which does this:
>
> function toForm() {
> document.form1.Firstname.focus();
> }
>
> It's called at body onLoad and this works fine. However, I'd like to
> make this code re-useable and place it in my site-wide javascript file.
> So I tried in my include file:
>
> function toForm(theForm, theField) {
> document.theForm.theField.focus();
> }
>
> and then called it by:
>
> onLoad="toForm('form1','Firstname')
>
> However, I was getting errors stating that theForm and theField were
> null objects. Anybody see what I'm doing wrong here?

> Second question. I would also like to include the functionality to click
