What is the correct way to check for undefined without causing the
browser to generate an error?

I have the following code, which works great under IE but Netscape
complains that 'item is undefined' (which is exactly what I want to
know, I just don't want it to error out and halt execution).

   with (document.frmUserEntry)
   {
      if (item('restSymbol') !=3D undefined)
         do
         {
   ...


The HTML for this page is generated dynamically by ASP, so I basically
just need to know whether or not this item exists on the page.  If it
exists, then I will continue processing it, otherwise I'll just skip it.

Thanks,
