Uh, the "language" attribute to the script tag has been deprecated
for, what, about 10 years now? Not the problem here, but...

yep, you don't have an array there in FF. Something like:

     var inputs = document.getElementsByTagName("input");
     var delusers = Array();
     for ( var j = 0; j < inputs.length; j++ )
     {
       if ( inputs[j].name == "delusers" )
       {
         delusers.push(inputs[j]);
       }
     }

:: would do it. Just one approach, TMTOWTDI.

   if ( delusers[i].checked )

   The error thrown in a try/catch block for your version is
     TypeError: delusers is not a function
   which is a pretty good clue, even if you're going glazed-eyed
   from staring at the same code block too long. :-)

HTH!
