[Javascript] Wacky unterminated string + alert + IFRAME error....

[TomMallard]

So what you're trying to do is dynamically write the alert box...hmmmm

ilSrc = "javascript:'document.write('+qt+'<script
language="JavaScript">alert("works!");</script>'+qt+');";

I'll have to play with this later...is this fired with onclick? You tried
eval(ilSrc);?
