setting page title dynamically using ExternalInterface.call()

Anyone know how to dynamically set the page title? I've seen various posts using ExternalInterface, but haven't been able to get it working with variables (hardcoded strings work fine though). Here's my latest attempt:

    var titleStr:String="window.document.title='"+userName+"'";
    ExternalInterface.call("eval('" + titleStr + "')");

Running this doesn't update the existing page title text.

[I prefer not to require a javascript function in HTML, and also prefer to avoid browserManager.]

Is there a simple way to get variables included somehow using ExternalInterface?

Thanks Lee, You are correct! The following works: 

var titleStr:String="window.document.title='"+userName+"'"; 
ExternalInterface.call("eval(" + titleStr + ")");

could the problem be the quote marks? 

your example becomes 
...call("eval('window.document.title='myUsername')'"); and eval argument 
string has inner and outer sets of '' - if JS is fine with that, ignore 
me ;)
