    Hello friend,

    Use below java script code in your program to print the addition of two numbers:
    HTML Code:
    <script type="text/javascript">
    function AddJavaSc()
    {
      var k, l;
      
      l=parseInt(document.getElementById("txtVal1").value);
      k=parseInt(document.getElementById("txtVal2").value);
      
    document.getElementById("txtVal3").value=l + k;
    
    }
    </script>

    <script language="JAVASCRIPT">
    function addTWONumbers()
    {
    var num1 = parseInt(document.getElementById("num value1").value);
    var num2 = parseInt(document.getElementById("num value2").value);
    var ansD = document.getElementById("Addition");
    ansTD.value = num1 + num2;
    }
    </script>
    </head>
    <Body text ="red">
    numvalue1 = <input type="text" name="numvalue1" id="numvalue1" value="1"/>

    Hi,

    To print the addition of two numbers using java script you need to use the one function. First you need to pass two numbers to that java script function. implement the "addition code" in the that function. The function will take two number as input and will give back the addition.
    HTML Code:
    function addDemo(v1, v2)
    {
    ans1.value = v1 + V2
    }

    I think you should use the alert function of the javascript to calculate addition. Use something below in you program:
    HTML Code:
    var t = '963';
    
    var y = '852;
    
    var h = parseInt(t) + parseInt(y);
    
    Alert(h); //It will show the addition

    {
    
    If (document.getElementById("BNM1").value == "")
    
    document.getElementById("BNM1").value= 0;
    
    If (document.getElementById("BNM2").value == "")
    
    document.getElementById("BNM2").value= 0;
    
    document.getElementById("BNM3").value= parseInt (document.getElementById("BNM1").value) + parseInt (document.getElementById("BNM2").value);
