Here is one solution using ids:

Code:

<html>
<head>

<script language="javascript" type="text/javascript">
    function fillcap() {
      
        var wire = document.getElementById("wire").value;
        var conduit = document.getElementById("cond").value;

        if (wire >= "10" && conduit == "1") {
            alert("Wire Size exceeds conduit max fill!")
        }  else {
            alert("Blah Blah!")
        }

    }
</script>

</head>
<body>
<form name="form">
        <h2>Fill Capacity</h2>

term::size::any

Term::Size::Any(3pm)					User Contributed Perl Documentation				      Term::Size::Any(3pm)

NAME

       Term::Size::Any - Retrieve terminal size

SYNOPSIS

	   # the traditional way
	   use Term::Size::Any qw( chars pixels );

	   ($columns, $rows) = chars *STDOUT{IO};
	   ($x, $y) = pixels;

DESCRIPTION

       This is a unified interface to retrieve terminal size.  It loads one module of a list of known alternatives, each implementing some way to
       get the desired terminal information. This loaded module will actually do the job on behalf of "Term::Size::Any".

       Thus, "Term::Size::Any" depends on the availability of one of these modules:

	   Term::Size		(soon to be supported)
	   Term::Size::Perl
	   Term::Size::ReadKey	(soon to be supported)
	   Term::Size::Win32

       This release fallbacks to Term::Size::Win32 if running in Windows 32 systems. For other platforms, it uses the first of Term::Size::Perl,
       Term::Size or Term::Size::ReadKey which loads successfully. (To be honest, I disabled the fallback to Term::Size and Term::Size::ReadKey
       which are buggy by now.)

   FUNCTIONS
       The traditional interface is by importing functions "chars" and "pixels" into the caller's space.

       chars
	       ($columns, $rows) = chars($h);
	       $columns = chars($h);

	   "chars" returns the terminal size in units of characters corresponding to the given filehandle $h.  If the argument is omitted,
	   *STDIN{IO} is used.	In scalar context, it returns the terminal width.

       pixels
	       ($x, $y) = pixels($h);
	       $x = pixels($h);

	   "pixels" returns the terminal size in units of pixels corresponding to the given filehandle $h.  If the argument is omitted, *STDIN{IO}
	   is used.  In scalar context, it returns the terminal width.

	   Many systems with character-only terminals will return "(0, 0)".

SEE ALSO

       It all began with Term::Size by Tim Goodwin. You may want to have a look at:

	   Term::Size
	   Term::Size::Perl
	   Term::Size::Win32
	   Term::Size::ReadKey
