[Javascript] Netscape object model : forms in div/layer

[Chris Basken]

the problem is: NS4.x sees a layer as its own document, so try...

	document.layers['LayoutLYR'].document.forms.length

this will, of course, crash IE.  thank you, have a nice flight.

my final solution was to write a function that cycled through the layers (if
any) and searched for forms in them.  if it found one, it would assign it to
an element in an array.  i would also do this for IE, but simply replicate
document.forms into my array.  once that was done, i could reference any
form on the page by using my array, and it would work for NS and IE.
