Works In FF But Not IE7 Please Help

Hey,

Could someone take a look at this and tell me why it does not appear to work in IE7 but is fine in FF please

Really don't get it, I am using Firebug to help me but I don't see that picking up anything either.

Thanks in advance!

EDIT: Ok I fixed it, I had to simply add the following line "x.document.close();" to this block of code below the document.write.

function newWindow(x) {
x.document.close();
x.document.open();
x.document.write(content);
x.moveTo(50,50);
x.focus();
}
