Not working right in IE

I have this javascript that is not working right in IE. At the top you see javascript for an online chat. The button is appearing at the bottom of the navigation in IE instead of at the top. In firefox its appearing right. Please help.



document.write("<div class='nav'>")
var lhnJsHost = (("https:" == document.location.protocol) ? "https://" : "https://");
document.write(unescape("%3Cscript src=" + lhnJsHost + "www.livehelpnow.net/lhn/scripts/lhnvisitor.aspx?div=&amp;zimg=32&amp;lhnid=8456&amp;iv=1&amp;iwidth=101&amp;iheight=35&amp;zzwindow=0&amp;d=0&amp;custom1=&amp;custom2=&amp;custom3=' type='text/javascript'%3E%3C/script%3E"))

You answered your own question:
The button is ‘appearing’ in a different location on different browsers. That is a CSS issue.
Take a look at your CSS and any necessary hacks for IE.

But how do i write the css for a javscript VAR?

You don’t. The javascript command “document.write” outputs HTML code (look at it carefully) directly to the browser.
Create/modify the CSS for ‘nav’, ‘nav_12’, et cetera.
