혼자 더듬거리면서.. 간단한계산기를 만들고있는데..

 

resultNum값은 잘출력이되는데

 

resultNum2 값은 출력자체가 되질않네요 ㅠㅠ 어디부분을 수정해야하나요..ㅠㅠ

 

<script type="text/javascript">

function Calc()

{
    var resultNum = 0;

    resultNum = ((document.testform.saserbe.value)*(document.testform.saserdon.value))/(document.testform.hewe.value);

    document.getElementById('CalcDiv').innerHTML = '(갯수x단가)/나눌갯수' + parseInt(resultNum) + '입니다.';
}
{
    var resultNum2 = 0;

    resultNum2 = ((document.testform.saserbe.value)*(document.testform.saserdon.value))-((document.testform.saserdon.value)+(document.resultNum.value));

    document.getElementById('CalcDiv').innerHTML = '손익'+ resultNum2 + '입니다.';

}
</script>
