[Javascript] Layer can't be accessed in IE

[Andrew Dunn]

Hi I have a problem with layers also,

I have a page that hides/shows layers when a user selects different options
from a radio button. But when I open the page in Netscape 4 the browser
crashes, i think this is due to the fact of the layers because when I
comment them out it works fine. I detect the browser type like so and set
variables according to the browser type:

function checkBrowser()
{
	if(navigator.userAgent.indexOf("MS") != -1)
	{
		isIE = true;
		layer = ".all";
		style = ".style";
	}
	else if(navigator.userAgent.indexOf("Nav") != -1)
	{
		isNav = true;
		layer = ".layers"
		style = "";
	}
	else
	{
		unSupported = true;
	}
}

I show and hide layers with lines like so:

eval("document" + layer + "['SectionT']" + style + ".visibility =
'visible'");

Can anyone see the flaw that would cause netscape to crash? This works fine
in IE.

Thank you.
Andrew
