If the error occurs at "line 0 character 0" then most likely it's the setTimeout that generates the error.

The command line inside the setTimeout is not considered part of your script. Thus you don't get the error at the line where the setTimeout is set, but instead at line 0 character 0.

I sometimes get similar errors, that's when there's something wrong with the command line inside the setTimeout (mispelling or case error).

In your case, it seems that the spelling and case are correct, so maybe it's just PHP (not-)adding elements that make your script wrong?

Have you checked the JS source after PHP processing?
I'd also try a scrollWindow test outside of the setTimeout.

If there's an error somewhere in the code, it should then make it easier to detect by indicating a line number.

scrollY = window.pageYOffset
}
else if (document.documentElement && document.documentElement.scrollTop)
{
scrollY = document.documentElement.scrollTop
}
else if (document.body)
{
scrollY = document.body.scrollTop
}

scrollY = window.pageYOffset;
parent.scrollY = scrollY;

temp = setTimeout('scrollWindow()',20);
}
function scrollWindow() {
