Netscape Clock Scripts Errors

I have a script that gets the time off the browser and sends the data to
Flash where I have an analog clock which sets the hrs, min and seconds
to the correct time.

I keep getting an error (only in Netscape, I'm using V4.6) one of which says "line 23 -
clock has no
properties".

Here is the url: http://wwwtest.yourfacility.com/ridgeauto.html

Here is one of the actual scripts from the page:

<SCRIPT LANGUAGE="JavaScript">
<!--
function klockan()
{
var clock = window.document.ridgeauto;
datum=new Date();
timmar=datum.getHours();
minuter=datum.getMinutes();
sekunder=datum.getSeconds();
clock.TGotoFrame('menu1_instance/time/sec', sekunder)
clock.TGotoFrame('menu1_instance/time/min', minuter)
clock.TGotoFrame('menu1_instance/time/hr', timmar);
setTimeout("klockan()",1000)
}
//-->
</script>

Thanks for any and all help!
