Hello Mparris ,

Here i have done the addition of 3 TextBox value in JavaScript and i am showing the result in p tag i.e (<p></p>).

Html:

<form id="form1" runat="server">
    <div>
        Black:
        <asp:TextBox ID="txtBlack" runat="server" /><br />
        Green:
        <asp:TextBox ID="txtGreen" runat="server" /><br />
        Gold:
        <asp:TextBox ID="txtGold" runat="server" /><br />
        Total:
        <p id="pSum">
        </p>
        <br />
        <asp:Button ID="btnCountSum" OnClientClick="CountSum();return false;" Text="Click Me"
            runat="server" />
    </div>
    <script type="text/javascript">
        function CountSum() {
            var black = document.getElementById("txtBlack").value;
            if (black == "") {
                black = "0";
            }
            var green = document.getElementById("txtGreen").value;
            if (green == "") {
                green = "0";
            }
            var gold = document.getElementById("txtGold").value;
            if (gold == "") {
                gold = "0";
            }
            var sum = parseInt(black) + parseInt(green) + parseInt(gold);
            if (!isNaN(sum)) {
                document.getElementById("pSum").innerHTML = sum;
            }
        }
        
    </script>
