firefox problem with accessing form value

[judy.j.miller]

Does anyone know why i can't access a form element value using dot
notation in firefox, when i'm in a function. Works ok in the body.
I'm trying to do this:

var FarTemp = faren.temp.value;

I can get at the value using the array method, the getelements by id
method, and the bracket-with-the-element-name in it method. But the
dot notation doesn't work, in firefox, in the function (which i have
in the head).

Thanks for any help.

That's not a valid reference to a form value, although some sloppy
browsers allow it:

var FarTemp = document.faren.temp.value;

is probably what you're looking for.

This is a typical error in accessing form values. Please visit

var FarTemp = document.forms["faren"].temp.value;
or
var FarTemp = document.forms["faren"].elements["temp"].value;

FormName.InputName.value
can be replaced with
document.forms["FormName"].InputName.value
or
document.forms["FormName"].elements["InputName"].value
