Required text fields & combos

Code:

---

<script LANGUAGE="JavaScript">
        <!--
        function checkrequired(which) {
        var pass=true;
        if (document.images) {
        for (i=0;i<which.length;i++) {
        var tempobj=which.elements[i];
        if (tempobj.name.substring(0,8)=="required") {if (((tempobj.type=='text'||tempobj.type=='textarea')&&tempobj.value=='')||(tempobj.type[0]=='s'&&tempobj.options[tempobj.selectedIndex].value=='')) {
        pass=false;
        break;
                }
        }
        }
        }
        if (!pass) {
        shortFieldName=tempobj.name.substring(8,30).toUpperCase();
        alert("Please make sure the all required fields are completed.");
        return false;
        }
        else
        return true;
        }
        -->
        </script>
        </head

just stick required before any input field name, and it works!

Combos should have no text in the first option
