I have a javascript in which I am trying to validate data and display error message in a label but the label is not displaying the error message. Below is my code.

Kindly help me with this issue.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="KUD.aspx.cs" Inherits="Javascript_Testing.KUD" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" language="javascript">
function ValidateForm() {
debugger;
var result = true;
if (document.getElementById("<%=txtFName.ClientID%>").innerText == "") {
document.getElementById("<%=errFName.ClientID%>").innerHTML = "First Name is required!";
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table border="1" style="border-style: solid">
<tr>
<td>
<asp:Label ID="lblFName" runat="server">First Name</asp:Label></td>
<td>
<asp:TextBox ID="txtFName" runat="server"></asp:TextBox></td>
<td>
<asp:Label ID="errFName" runat="server"></asp:Label></td>
</tr>
<tr>

<asp:Label ID="lblLName" runat="server">Last Name</asp:Label></td>
<td>
<asp:TextBox ID="txtLName" runat="server"></asp:TextBox></td>

<asp:Label ID="errLName" runat="server"></asp:Label></td>
</tr>
<tr>
<td>
<asp:Label ID="lblEmail" runat="server">E-Mail</asp:Label></td>
<td>
<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox></td>
<td>
<asp:Label ID="errEmail" runat="server"></asp:Label></td>
</tr>
<tr>
<td>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" OnClientClick="ValidateForm()" />
</td>
