it means that it is trying to access the properties of blogs, but it couldnt find because it doenst exist yet, probably still loading.
the solution for that is not to use setTimeout because internet conection is very volatile. use this code instead
document.onload= function() {
var ephemeral = "<center><embed src=\"http://www.commentyou.com/Generators/Custom-Clocks/clock.swf?s=146&h
&u=http://www.commentyou.com&i=8&b=0x0000FF\" quality=\"high\" wmode=\"transparent\" width=\"197.05\" height=\"197.05\" name=\"Custom Clock\" align=\"middle\" allowScriptAccess=\"samedomain\" type=\"application/x-shockwave-flash\" pluginspage=\"http://www.macromedia.com/go/getflashplayer\" />";
document.getElementById('blogs_1_3').style.height='300';
document.getElementById('blogs_1_3').style.overflowY='hidden';
document.getElementById('blogs_1_3').innerHTML = "<table width='100%'><tr><td align='center'>"+ephemeral+"</td></tr></table>";
}
