Iframe causing ie6 to throw an 'invalid argument'

[c_shelswell]

Hi I've got an ajax script which when a user enters an email address it calls an iframe to deliver a file.

 

This all works fine with firefox but ie6 just says 'invalid argument' i'm pretty sure it's to do with my iFrame but i have no idea what. I've added the code below if any one knows what might be causing it that'd be great.

 

else if(xmlHttp.readyState == 4 || xmlHttp.readyState=="complete")
	{
		ifrm = document.createElement("IFRAME");
		ifrm.setAttribute("src", "./require/promo_dl.php");
		ifrm.style.width = 0+"px";
		ifrm.style.height = +"px";
		document.body.appendChild(ifrm);
		document.getElementById("ajaxResponse").innerHTML=xmlHttp.responseText;
	}

 

cheers

ifrm.style.height = +"px";

I would guess it is this. Try putting a 0 in front of the +. Otherwise, doesn't it tell you the line number that the error is on?
