        if(check.checked==true){
             document.getElementById("licensenum").disabled=false;
             document.getElementById("reservedaynum").disabled=false;
        }else {
            document.getElementById("licensenum").disabled=true;
            document.getElementById("licensenum").value=0;
            document.getElementById("reservedaynum").disabled=true;
            document.getElementById("reservedaynum").value=0;
