This works

Code:

<html>
<head>
<script language="javascript" type="text/javascript">

function TxtMsg(){

if( (document.forms['LoginFrm'].UserName.value=="") || (document.forms['LoginFrm'].Password.value=="") )
{
   alert("Please enter User Name and Password ");
   return false;
}

}

</script>

<body>
<form name="LoginFrm" method="post" action="work.html" onSubmit="return TxtMsg();">
User Name <input type="text" name="UserName" />&nbsp;&nbsp;&nbsp;
Password <input type="password" name="Password" />&nbsp;&nbsp;&nbsp;
<input type="Submit" name="SignIn" value="Sign In" />&nbsp;&nbsp;&nbsp;
<a href="jacob.php">Forgot Password/ID </a>&nbsp;&nbsp;
<a href="logout.php">Logout </a>
</form>
</body>
</html>
