Legend not showing up in IE

[Dylan Beaudette]

Interesting.

Fixed the empty color string.

I have been puzzling over the "document.layers" error on the javascript 
console for a while now.

Looking into the source of the main landview application source file, i see a 
couple references to document.layers:

function checkLegendControls(element) {
 
 for (var i=0; i<element.length; i++) {
    var maxscaleObj = eval("document.layers." + element[i].value + 
"Maxscale");
    var minscaleObj = eval("document.layers." + element[i].value + 
"Minscale");
    if (maxscaleObj) {
      if (maxscaleObj.value < ms.getscale()) {
        disableLegendControls(element[i]);
        continue;
      }
    }
    if (minscaleObj) {
      if (minscaleObj.value > ms.getscale()) {
        disableLegendControls(element[i]);
      }
    }
  }
}


and it looks like this function is run from the postdraw() function with:
checkLegendControls(document.layers.foreground);
checkLegendControls(document.layers.background);


Note that I am not including a "layers=" string in my URL passed to the 
mapserver CGI.

Cheers,
