prohibit two words

<script type="text/javascript">
<!--

function chkFrm(){

illChar = "FK";
var doc = document['oFrm'];

if(doc['say'].value.toUpperCase().indexOf(illChar,0) != -1){
alert(illChar + " is prohibited!");
return false;
}
}

//-->
</script>

<form name="oFrm" onsubmit="return chkFrm();" action="action.htm" method="post">
<textarea name="say" rows="10" cols="25"></textarea>
<br />
<input type="submit" value="Check Form" />
</form>


The above code probibits the word "FK."

Then, how can I prohibit two words "FK" and "ST."

I tried to change the prohibited word part like the following, but failed.

illChar = "FK,ST";


Thanks in Advance

I don't quite understand.
The previous post was about one prohibited word.
This is about two prohibited word.
So I thought this is a new post.

Should I post it as related post to the previous post?

Give my greedy up

Definitely! That would be my advice every time.

And please don't thank people who you want to oblige you with a favour IN ADVANCE. The time to make your gratitude known is AFTER the assistance has been supplied. Thanks in advance for not thanking people in advance in future.
