Thought I would go ahead and post a bit more on this, so here is my
wordcount little function on the textarea of the form:

    <textarea name="Comments" cols="55" rows="5" wrap="hard"
onKeyDown="wordCounter(this.form.Comments,this.form.remLen, 300);"
onKeyUp="wordCounter(this.form.Comments,this.form.remLen, 300);"><?php if
(isset($_SESSION['Comments'])) {echo $_SESSION['Comments'];}
?></textarea><br>Letters to the Editor are limited to 300 words or
less.<br>Words remaining: <input type=box readonly name=remLen size=3

So I was thinking I should be able to pass that again to the next page which
is the emailform.php page that is taking all the id= and printing them to an
email ....
should be able to reuse that function right?

<input type="hidden" id="words"  value="" onSubmit="return
wordCounter(this.form.Comments,this.form.remLen);" >

or do I need to define the variable? think I'm starting to confuse myself
