Validation script not working in Firefox

I am finding that my JS validation script isn’t working in Firefox (but does in IE) since I changed the field names to begin with a letter. Anyone know why?

I have form fields that look like this:

<input type="text" name="a_Name" size="18" />

<input type="text" name="b_Email" size="18" />

The form action tag looks like this:

<form action="../gdform.php " method="post" name="Guestbook" id="Guestbook" onsubmit="this.c_Company.optional=true;this.d_Street.optional=true;this.e_Suite.optional=true;this.f_City.optional=true;this.g_State.optional=true;this.h_Country.optional=true;this.i_Zipcode.optional=true;this.j_WorkPhone.optional=true;return verify(this);">

And the javascript validation script looks like this:


// A utility function that returns true if a string contains only 
// whitespace characters

function isblank(s) {
    for(var i = 0; i < s.length; i++) {
        var c = s.charAt(i);
        if ((c != ' ') && (c != '
') && (c != '    ')) return false;
    }
    return true;
}


// This is the function that performs form verification. It is invoked
// from the onsubmit event handler. The handler should return whatever
// value this function returns.

function verify(f) {
    var msg;
    var empty_fields = "";
    var errors = "";

    // Loop through the elements of the form, looking for all Text and 
    // Textarea elements that don't have an "optional" property defined. 
    // Then check for fields that are empty and make a list of them. Also, if
    // any of these elements have a "min" or a "max" property defined, verify
    // that they are numbers and are in the right range. If the element has a
    // "numeric" property defined, verify that it is a number, but don't check
    // its range. Put together error messages for fields that are wrong.

    for(var i = 0; i < f.length; i++) {
        var e = f.elements*;

        if (((e.type == "text") || (e.type == "textarea")) && !e.optional) {
            // First check if the field is empty
            if ((e.value == null) || (e.value == "") || isblank(e.value)) {
                empty_fields += "
          " + e.name;
                continue;
            }

            // Now check for fields that are supposed to be numeric
            // Example: onSubmit="this.Zipcode.numeric=true;return verify(this);"
            if (e.numeric) { 
                var v = parseFloat(e.value);
                if (isNaN(v)) {
                    errors += "- Zipcode needs to be a number.
";
                }
                if (e.value.length < 5) {
                    errors += "- You have entered an invalid Zipcode.
";
                }
            }
        }
    }
    var checkEmail = Guestbook.b_Email.value
    if ((checkEmail.indexOf('@') < 0) || ((checkEmail.charAt(checkEmail.length-4) != '.') && (checkEmail.charAt(checkEmail.length-3) != '.')))
    {
        errors += "- You have entered an invalid email address.
";
        Guestbook.b_Email.select();
        //return false;
    }

    if (Guestbook.i_Zipcode.value.length < 5) {
        errors += "- You have entered an invalid Zipcode.
";
    }
    if (Guestbook.g_State.selectedIndex == 0) {
        errors += "- Please select a State or Province.
";
        returnStatus = 0;
    };
    if (Guestbook.h_Country.selectedIndex == 0) {
        errors += "- Please select a Country.";
        returnStatus = 0;
    };


    // Now, if there were any errors, display the messages, and
    // return false to prevent the form from being submitted. 
    // Otherwise, return true.

    if (!empty_fields && !errors) return true;
    msg  = "___________________________________________________

"
    msg += "The form was not submitted because of the following error(s).
";
    msg += "Please correct these error(s) and re-submit.
";
    msg += "___________________________________________________

"


    if (empty_fields) {
        msg += "- The following required field(s) are empty:" 
                + empty_fields + "
";
        if (errors) msg += "
";
    }
    msg += errors;
    alert(msg);
    return false;
}

Adding the letter to the beginning of the field name helps with a PHP script problem - it alpha orders the field names.
