[SOLVED] simple javascript display function not working?

[sayedsohail]

Hi everyone,

 

If i use alert("status is " + request.status);, it works fine.

 

but if pass the response into function update("Status is:"+request.status);, than it says error.

 

function update(str)
{
document.getElementById("popmess").innerHTML=str;  //popmess is div element with an id=popmess.
}

 

Is something wrong with my script.?
