NIS Destroys Page
<p>
<script language="JavaScript">
c="More text that doesn't appear on the crashed page.";
c+=h3; // some more text from src=common_help.js
document.write(c);
if(window.SymError){alert("Error message for NIS Ad Blocking broken page goes here.")}
</script>
Below my name is a copy from View/Source of the above after the Norton Internet Security (NIS) Ad Blocking feature has finished with it. I am not trying to solve the problem with NIS; I simply want to issue an error message telling my users to turn off Ad Blocking if they want to use my page. I used to be able to do this with the following code:
if(window.SymError){alert("Error message for NIS Ad Blocking broken page goes here.")}
But it no longer works. Any ideas why?
Thanks, Peter (complete View/Source code below)

<p>
That seems to still be in the <head> of the page. Also, you then try to do a document.write, also in the <head>.
