First,
if(sel = 'group'). Here sel is an object.You can not compare an object with any variable.
Second,
if(sel = 'group'). Here you have used "=" sign but not "==" sign.This syntax would never compare but it assigns.
Third.
var opt = sel.options[sel.selectedIndex].value;
Here 'opt' value will always be null as you have not assigned anything to it.
You need to modify your statement,
<option>group</option> with <option value="somevalue">group</option>
Here is the complete code.

--------------------------
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<title>New Page 1</title>
<script language = javascript>
function cf(its)
{
var sel = document.its.D1;
var txt = sel.options[sel.selectedIndex].text;
var opt = sel.options[sel.selectedIndex].value;
if(opt == 'group')// OR if(txt == 'group') bcoz both values are same
{
alert("Select a Group");
return false;
}
}
</script>
</head>
<body>
<form method="POST" name = "its" action="--WEBBOT-SELF--" onSubmit="return cf(this);">
<p><select size="1" name="D1">
<option value = "group">group</option>
<option value = "1">1</option>
<option value = "2">2</option>
</select><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
</body>
</html>
---------------------------

If you want to become a rich, do not work for others but make others to work for you.

NOTE :

if(its.D1.value = 'Select a Group')
(1) Where you havae assigned this value?
(2) You do not have "<option value = "Select a Group">Select a Group</option> " statement in your code.
(3) As I mentioned earliar, use "==" operator for comparison but not "=".
(4) I did not understand why are using this statement?If this statment true, than other will be false and vice versa.
Bcoz if this is true, your code if(opt == 'group') will never be
true and if this is false, than too.In any case your if(opt == 'group') is not going to be true.

The more you say urgent the less I want to help you.
This code works that I posted, I do not know why you said it does not work.
I select the first option and it does not submit and I get the error. I submit another option and the form submits.

alert("Select a Group");
return false;
}
else{
return true;
}
}
</script>
</head>
<body>
<form method="POST" name = "its" action="--WEBBOT-SELF--" onSubmit="return cf();">
<p><select size="1" name="D1">
<option value = "group">group</option>
<option value = "1">1</option>
<option value = "2">2</option>
</select><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
</body>

This is a friendly place and every ranchers are benifited.No one is going to pay here for solving your problems.Everyone has his/her own work and everyone's work is urgent.If you say your works is URGENT !!!, it does not mean that people will keep aside their work and first they will solve your problem.If someone voluntarily devotes their valuable time to help others, we should appriciate him/her.Everyone are free to reply at their own time.Mentioning URGENT just annoy others.And it is not advisable to ask for help for a problem which you can solve yourself.If you had just googled it with your problem,you would have got answer yourself.This would save person's precious time.
